In order to provide pre-compiled binaries of third-party applications for FreeBSD, the Ports Collection is regularly built on one of the “Package Building Clusters.” Currently, the main cluster in use is at http://pointyhat.FreeBSD.org.
This article documents the internal workings of the cluster.
Note: Many of the details in this article will be of interest only to those on the Ports Management team.
Most of the package building magic occurs under the /var/portbuild directory. Unless otherwise specified, all paths will be relative to this location. ${arch} will be used to specify one of the package architectures (e.g., amd64, arm, i386™, ia64, powerpc, SPARC64®), and ${branch} will be used to specify the build branch (e.g., 7, 7-exp, 8, 8-exp, 9, 9-exp, 10, 10-exp). The set of branches that portmgr currently supports is the same as those that the FreeBSD security team supports.
Note: Packages are no longer built for branches 4, 5, or 6, nor for the alpha architecture.
The scripts that control all of this live in /var/portbuild/scripts/. These are the checked-out copies from the Subversion repository at base/projects/portbuild/scripts/ .
Typically, incremental builds are done that use previous packages as dependencies; this takes less time, and puts less load on the mirrors. Full builds are usually only done:
right after release time, for the -STABLE branches
periodically to test changes to -CURRENT
for experimental ("exp-") builds
Packages from experimental builds are not uploaded.
Until mid-2010, the scripts were completely specific to pointyhat.FreeBSD.org as the head (dispatch) node. During the summer of 2010, a significant rewrite was done in order to allow for other hosts to be head nodes. Among the changes were:
removal of the hard-coding of the string pointyhat
factoring out all configuration constants (which were previously scattered throughout the code) into configuration files (see below)
appending the hostname to the directories specified by buildid (this will allow directories to be unambigious when copied between machines.)
making the scripts more robust in terms of setting up directories and symlinks
where necessary, changing certain script invocations to make all the above easier
This document was originally written before these changes were made. Where things such as script invocations have changed, they were denoted as new codebase: as opposed to old codebase:.
Note: Up until November 2012, pointyhat had still been running the old codebase. That installation has now been permanently offlined. Therefore, all the instructions having to do with the old codebase have been removed.
Note: Also during this process, the codebase was migrated to the Subversion repository. For reference, the previous version may still be found in CVS.
The i386 clients co-located with pointyhat netboot from it (connected nodes); all other clients (disconnected nodes) are either self-hosted or netboot from some other pxe host. In all cases they set themselves up at boot-time to prepare to build packages.
The cluster master rsyncs the interesting data (ports and src trees, bindist tarballs, scripts, etc.) to disconnected nodes during the node-setup phase. Then, the disconnected portbuild directory is nullfs-mounted for jail builds.
The ports-${arch} user can ssh(1) to the client nodes to monitor them. Use sudo and check the portbuild.hostname.conf for the user and access details.
The scripts/allgohans script can be used to run a command on all of the ${arch} clients.
Package builds are performed in a jail populated by the portbuild script using the ${arch}/${branch}/builds/${buildid}/bindist.tar file.
The makeworld command builds a world from the ${arch}/${branch}/builds/${buildid}/src/ tree and installs it into ${arch}/${branch}/builds/${buildid}/bindist.tar. The tree will be updated first unless -novcs is specified. It should be run as root:
# /var/portbuild/scripts/makeworld ${arch} ${branch} ${buildid} [-novcs]
The bindist.tar tarball is created from the previously installed world by the mkbindist script. It should be also be run as root:
# /var/portbuild/scripts/mkbindist ${arch} ${branch} ${buildid}
The per-machine tarballs are located in ${arch}/clients.
The bindist.tar file is extracted onto each client at client boot time, and at the start of each pass of the dopackages script.
For both commands above, if ${buildid} is latest, it may be omitted.
You can customize your build by providing local versions of make.conf and/or src.conf, named ${arch}/${branch}/builds/${buildid}/make.conf.server and ${arch}/${branch}/builds/${buildid}/src.conf.server, respectively. These will be used in lieu of the default-named files on the server side.
Similarly, if you wish to also affect the client-side make.conf, you may use ${arch}/${branch}/builds/${buildid}/make.conf.client.
Note: Due to the fact that individual clients may each have their own per-host make.conf, the contents of ${arch}/${branch}/builds/${buildid}/make.conf.client will be appended to that make.conf, not supplant it, as is done for ${arch}/${branch}/builds/${buildid}/make.conf.server.
Note: There is no similar functionality for ${arch}/${branch}/builds/${buildid}/src.conf.client (what effect would it have?).
Example 1. Sample make.conf.target to test new default ruby version
(For this case, the contents are identical for both server and client.)
RUBY_DEFAULT_VER= 1.9
Example 2. Sample make.conf.target for clang builds
(For this case, the contents are also identical for both server and client.)
.if !defined(CC) || ${CC} == "cc" CC=clang .endif .if !defined(CXX) || ${CXX} == "c++" CXX=clang++ .endif .if !defined(CPP) || ${CPP} == "cpp" CPP=clang-cpp .endif # Do not die on warnings NO_WERROR= WERROR=
Separate builds for various combinations of architecture and branch are supported. All data private to a build (ports tree, src tree, packages, distfiles, log files, bindist, Makefile, etc) are located under the ${arch}/${branch}/builds/${buildid}/ directory. The most recently created build can be alternatively referenced using buildid latest, and the one before using previous.
New builds are cloned from the latest, which is fast since it uses ZFS.
The scripts/dopackages.wrapper script is used to perform the builds.
# dopackages.wrapper ${arch} ${branch} ${buildid} [-options]
Most often, you will be using latest for the value of buildid.
[-options] may be zero or more of the following:
-keep
- Do not delete this build in the future, when
it would be normally deleted as part of the latest - previous cycle. Do not forget to clean it up manually when you
no longer need it.
-nofinish
- Do not perform post-processing once the
build is complete. Useful if you expect that the build will need to be restarted
once it finishes. If you use this option, do not forget to cleanup the
clients when you do not need the build any more.
-finish
- Perform post-processing only.
-nocleanup
- By default, when the -finish
stage of the build is complete, the build data will
be deleted from the clients. This option will prevent that.
-restart
- Restart an interrupted (or non-finished) build from the beginning. Ports that failed on the
previous build will be rebuilt.
-continue
- Restart an interrupted (or non-finished) build. Will not rebuild ports that failed on the
previous build.
-incremental
- Compare the interesting fields of the
new INDEX with the previous one, remove packages
and log files for the old ports that have changed, and rebuild the rest. This
cuts down on build times substantially since unchanged ports do not get rebuilt
every time.
-cdrom
- This package build is intended to end up on
a CD-ROM, so NO_CDROM packages and distfiles should
be deleted in post-processing.
-nobuild
- Perform all the preprocessing steps, but
do not actually do the package build.
-noindex
- Do not rebuild INDEX during preprocessing.
-noduds
- Do not rebuild the duds file (ports that are never built, e.g., those marked IGNORE, NO_PACKAGE, etc.) during
preprocessing.
-nochecksubdirs
- Do not check the SUBDIRS for ports that are not connected to the build.
-trybroken
- Try to build BROKEN ports (off by default because the amd64/i386 clusters are fast enough now that when doing
incremental builds, more time was spent rebuilding things that were going to
fail anyway. Conversely, the other clusters are slow enough that it would be a
waste of time to try and build BROKEN ports).
Note: With
-trybroken
, you probably also want to use-fetch-original
and-unlimited-errors
.
-nosrc
- Do not update the src tree from the ZFS snapshot, keep the tree from previous
build instead.
-srcvcs
- Do not update the src tree from the ZFS snapshot, update it with a fresh
checkout instead.
-noports
- Do not update the ports tree from the ZFS snapshot, keep the tree from previous
build instead.
-portsvcs
- Do not update the ports tree from the ZFS snapshot, update it with a fresh
checkout instead.
-norestr
- Do not attempt to build RESTRICTED ports.
-noplistcheck
- Do not make it fatal for ports to
leave behind files after deinstallation.
-nodistfiles
- Do not collect distfiles that pass
make checksum for later uploading to ftp-master.
-fetch-original
- Fetch the distfile from the
original MASTER_SITES rather than any cache such as on ftp-master.
-unlimited-errors
- defeat the "qmanager threshhold"
check for runaway builds. You want this primarily when doing a -restart
of a build that you expect to mostly fail, or
perhaps a -trybroken
run. By default, the threshhold
check is done.
Unless you specify -restart
, -continue
, or -finish
, the
symlinks for the existing builds will be rotated. i.e, the existing symlink for previous will be deleted; the most recent build will have its
symlink changed to previous/; and a new build will be
created and symlinked into latest/.
If the last build finished cleanly you do not need to delete anything. If it was
interrupted, or you selected -nocleanup
, you need to
clean up clients by running
% build cleanup ${arch} ${branch} ${buildid} -full
When a new build is created, the directories errors/, logs/, packages/, and so forth, are cleaned by the scripts. If you are short of space, you can also clean out ports/distfiles/. Leave the latest/ directory alone; it is a symlink for the webserver.
Note: dosetupnodes is supposed to be run from the dopackages script in the
-restart
case, but it can be a good idea to run it by hand and then verify that the clients all have the expected job load. Sometimes, dosetupnode cannot clean up a build and you need to do it by hand. (This is a bug.)
Make sure the ${arch} build is run as the ports-${arch} user or it will complain loudly.
Note: The actual package build itself occurs in two identical phases. The reason for this is that sometimes transient problems (e.g., NFS failures, FTP sites being unreachable, etc.) may halt a build. Doing things in two phases is a workaround for these types of problems.
Be careful that ports/Makefile does not specify any empty subdirectories. This is especially important if you are doing an -exp build. If the build process encounters an empty subdirectory, both package build phases will stop short, and an error similar to the following will be written to ${arch}/${branch}/journal:
don't know how to make dns-all(continuing)
To correct this problem, simply comment out or remove the SUBDIR entries that point to empty subdirectories. After doing
this, you can restart the build by running the proper dopackages command with the -restart
option.
Note: This problem also appears if you create a new category Makefile with no SUBDIRs in it. This is probably a bug.
Example 6. Update the i386-7 tree and do a complete build
% dopackages.wrapper i386 7 -nosrc -norestr -nofinish
Example 7. Restart an interrupted amd64-8 build without updating
% dopackages.wrapper amd64 8 -nosrc -noports -norestr -continue -noindex -noduds -nofinish
Hint: it is usually best to run the dopackages command inside of screen(1).
You may need to manipulate the build data before starting it, especially for experimental builds. This is done with the build command. Here are the useful options for creation:
build create arch branch [newid] - Creates newid (or a datestamp if not specified). Only needed when bringing up a new branch or a new architecture.
build clone arch branch oldid [newid] - Clones oldid to newid (or a datestamp if not specified).
build srcupdate arch branch buildid - Replaces the src tree with a new ZFS snapshot. Do not forget to use -nosrc flag to dopackages later!
build portsupdate arch branch buildid - Replaces the ports tree with a new ZFS snapshot. Do not forget to use -noports flag to dopackages later!
Sometimes there is a need to rebuild a single package from the package set. This can be accomplished with the following invocation:
# path/qmanager/packagebuild amd64 7-exp 20080904212103 aclock-0.2.3_2.tbz
A full build without any -no options performs the following operations in the specified order:
An update of the current ports tree from the ZFS snapshot[1]
An update of the running branch's src tree from the ZFS snapshot[1]
Checks which ports do not have a SUBDIR entry in their respective category's Makefile[1]
Creates the duds file, which is a list of ports not to build[1][2]
Builds packages (phase 1)[3]
Performs another node setup[1]
Builds packages (phase 2)[3]
There are several cases where you will need to manually clean up a build:
You have manually interrupted it.
The head node has been rebooted while a build was running.
qmanager has crashed and has been restarted.
Manually interrupting a build is a bit messy. First you need to identify the tty in which it's running (either record the output of tty(1) when you start the build, or use ps x to identify it. You need to make sure that nothing else important is running in this tty, e.g., ps -t p1 or whatever. If there is not, you can just kill off the whole term easily with pkill -t pts/1; otherwise issue a kill -HUP in there by, for example, ps -t pts/1 -o pid= | xargs kill -HUP. Replace p1 by whatever the tty is, of course.
The package builds dispatched by make to the client machines will clean themselves up after a few minutes (check with ps x until they all go away).
If you do not kill make(1), then it will spawn more jobs. If you do not kill dopackages, then it will restart the entire build. If you do not kill the pdispatch processes, they'll keep going (or respawn) until they've built their package.
To free up resources, you will need to clean up client machines by running build cleanup command. For example:
% /var/portbuild/scripts/build cleanup i386 8-exp 20080714120411 -full
If you forget to do this, then the old build jails will not be cleaned up for 24 hours, and no new jobs will be dispatched in their place since pointyhat thinks the job slot is still occupied.
To check, cat ~/loads/* to display the status of client machines; the first column is the number of jobs it thinks is running, and this should be roughly concordant with the load average. loads is refreshed every 2 minutes. If you do ps x | grep pdispatch and it is less than the number of jobs that loads thinks are in use, you are in trouble.
You may have problem with the umount commands hanging. If so, you are going to have to use the allgohans script to run an ssh(1) command across all clients for that buildenv. For example:
% ssh gohan24 df
will get you a df, and
% allgohans "umount -f pointyhat.freebsd.org:/var/portbuild/i386/8-exp/ports" % allgohans "umount -f pointyhat.freebsd.org:/var/portbuild/i386/8-exp/src"
are supposed to get rid of the hanging mounts. You will have to keep doing them since there can be multiple mounts.
Note: Ignore the following:
umount: pointyhat.freebsd.org:/var/portbuild/i386/8-exp/ports: statfs: No such file or directory umount: pointyhat.freebsd.org:/var/portbuild/i386/8-exp/ports: unknown file system umount: Cleanup of /x/tmp/8-exp/chroot/53837/compat/linux/proc failed! /x/tmp/8-exp/chroot/53837/compat/linux/proc: not a file system root directoryThe former two mean that the client did not have those mounted; the latter two are a bug.
You may also see messages about procfs.
After you have done all the above, remove the ${arch}/lock file before trying to restart the build. If you do not, dopackages will simply exit.
If you have to do a ports tree update before restarting, you may have to rebuild either duds, INDEX, or both.
Here are the rest of the options for the build command:
build destroy arch branch - Destroy the build id.
build list arch branch - Shows the current set of build ids.
You can use qclient command to monitor the status of build nodes, and to list the currently scheduled jobs:
% python path/qmanager/qclient jobs % python path/qmanager/qclient status
The scripts/stats ${branch} command shows the number of packages already built.
Running cat /var/portbuild/*/loads/* shows the client loads and number of concurrent builds in progress. The files that have been recently updated are the clients that are online; the others are the offline clients.
Note: The pdispatch command does the dispatching of work onto the client, and post-processing. ptimeout.host is a watchdog that kills a build after timeouts. So, having 50 pdispatch processes but only 4 ssh(1) processes means 46 pdispatches are idle, waiting to get an idle node.
Running tail -f ${arch}/${branch}/build.log shows the overall build progress.
If a port build is failing, and it is not immediately obvious from the log as to why, you can preserve the WRKDIR for further analysis. To do this, touch a file called .keep in the port's directory. The next time the cluster tries to build this port, it will tar, compress, and copy the WRKDIR to ${arch}/${branch}/wrkdirs/.
If you find that the system is looping trying to build the same package over and over again, you may be able to fix the problem by rebuilding the offending package by hand.
If all the builds start failing with complaints that they cannot load the dependent packages, check to see that httpd is still running, and restart it if not.
Keep an eye on df(1) output. If the /var/portbuild file system becomes full then Bad Things™ happen.
The status of all current builds is generated periodically into the packagestats.html file, e.g., http://pointyhat.FreeBSD.org/errorlogs/packagestats.html. For each buildenv, the following is displayed:
updated is the contents of .updated. This is why we recommend that you update .updated for -exp runs (see below).
date of latest log
number of lines in INDEX
the number of current build logs
the number of completed packages
the number of errors
the number of duds (shown as skipped)
missing shows the difference between INDEX and the other columns. If you have restarted a run after a ports tree update, there will likely be duplicates in the packages and error columns, and this column will be meaningless. (The script is naive).
running and completed are guesses based on a grep(1) of build.log.
The easiest way to track build failures is to receive the emailed logs and sort them to a folder, so you can maintain a running list of current failures and detect new ones easily. To do this, add an email address to ${branch}/portbuild.conf. You can easily bounce the new ones to maintainers.
After a port appears broken on every build combination multiple times, it is time to mark it BROKEN. Two weeks' notification for the maintainers seems fair.
Note: To avoid build errors with ports that need to be manually fetched, put the distfiles into ~ftp/pub/FreeBSD/distfiles. Access restrictions are in place to make sure that only the build clients can access this directory.
When building packages for a release, it may be necessary to manually update the ports and src trees to the release tag and
use -novcs
and -noportsvcs
.
To build package sets intended for use on a CD-ROM, use the -cdrom
option to dopackages.
If the disk space is not available on the cluster, use -nodistfiles
to avoid collecting distfiles.
After the initial build completes, restart the build with -restart -fetch-original
to collect updated distfiles as well.
Then, once the build is post-processed, take an inventory of the list of files
fetched:
% cd ${arch}/${branch} % find distfiles > distfiles-${release}
This inventory file typically lives in i386/${branch} on the cluster master.
This is useful to aid in periodically cleaning out the distfiles from ftp-master. When space gets tight, distfiles from recent releases can be kept while others can be thrown away.
Once the distfiles have been uploaded (see below), the final release package set must
be created. Just to be on the safe side, run the ${arch}/${branch}/cdrom.sh script by hand to make sure all
the CD-ROM restricted packages and distfiles have been pruned. Then, copy the ${arch}/${branch}/packages directory to ${arch}/${branch}/packages-${release}. Once the packages are safely moved off,
contact the Release Engineering Team <[email protected]>
and inform them of the
release package location.
Remember to coordinate with the Release Engineering Team <[email protected]>
about the timing and status
of the release builds.
Once a build has completed, packages and/or distfiles can be transferred to ftp-master for propagation to the FTP mirror network. If the build
was run with -nofinish
, then make sure to follow up with dopackages -finish to post-process the packages (removes RESTRICTED and NO_CDROM packages where
appropriate, prunes packages not listed in INDEX, removes from
INDEX references to packages not built, and generates a CHECKSUM.MD5 summary); and distfiles (moves them from the temporary
distfiles/.pbtmp directory into distfiles/ and removes RESTRICTED and NO_CDROM distfiles).
It is usually a good idea to run the restricted.sh and/or cdrom.sh scripts by hand after dopackages finishes just to be safe. Run the restricted.sh script before uploading to ftp-master, then run cdrom.sh before preparing the final package set for a release.
The package subdirectories are named by whether they are for release, stable, or current. Examples:
packages-7.2-release
packages-7-stable
packages-8-stable
packages-9-stable
packages-10-current
Note: Some of the directories on ftp-master are, in fact, symlinks. Examples:
packages-stable
packages-current
Be sure you move the new packages directory over the real destination directory, and not one of the symlinks that points to it.
If you are doing a completely new package set (e.g., for a new release), copy packages to the staging area on ftp-master with something like the following:
# cd /var/portbuild/${arch}/${branch} # tar cfv - packages/ | ssh portmgr@ftp-master tar xfC - w/ports/${arch}/tmp/${subdir}
Then log into ftp-master, verify that the package set was transferred successfully, remove the package set that the new package set is to replace (in ~/w/ports/${arch}), and move the new set into place. (w/ is merely a shortcut.)
For incremental builds, packages should be uploaded using rsync so we do not put too much strain on the mirrors.
ALWAYS use -n
first with rsync and check the output
to make sure it is sane. If it looks good, re-run the rsync
without the -n
option.
Example rsync command for incremental package upload:
# rsync -n -r -v -l -t -p --delete packages/ portmgr@ftp-master:w/ports/${arch}/${subdir}/ | tee log
Distfiles should be transferred with the cpdistfiles script:
# /var/portbuild/scripts/cpdistfiles ${arch} ${branch} ${buildid} [-yesreally] | tee log2
Doing it by hand is deprecated.
Experimental patches builds are run from time to time to new features or bugfixes to the ports infrastructure (i.e. bsd.port.mk), or to test large sweeping upgrades. At any given time there may be several simultaneous experimental patches branches, such as 8-exp on the amd64 architecture.
In general, an experimental patches build is run the same way as any other build, except that you should first update the ports tree to the latest version and then apply your patches. To do the former, you can use the following:
Note: The following example is obsolete
% cvs -R update -dP > update.out % date > .updated
This will most closely simulate what the dopackages script does. (While .updated is merely informative, it can be a help.)
You will need to edit update.out to look for lines beginning with ^M, ^C, or ^? and then deal with them.
It is always a good idea to save original copies of all changed files, as well as a list of what you are changing. You can then look back on this list when doing the final commit, to make sure you are committing exactly what you tested.
Since the machine is shared, someone else may delete your changes by mistake, so keep a copy of them in e.g., your home directory on freefall. Do not use tmp/; since pointyhat itself runs some version of -CURRENT, you can expect reboots (if nothing else, for updates).
In order to have a good control case with which to compare failures, you should first do a package build of the branch on which the experimental patches branch is based for the i386 architecture (currently this is 8). Then, when preparing for the experimental patches build, checkout a ports tree and a src tree with the same date as was used for the control build. This will ensure an apples-to-apples comparison later.
Once the build finishes, compare the control build failures to those of the experimental patches build. Use the following commands to facilitate this (this assumes the 8 branch is the control branch, and the 8-exp branch is the experimental patches branch):
% cd /var/portbuild/i386/8-exp/errors % find . -name \*.log\* | sort > /tmp/8-exp-errs % cd /var/portbuild/i386/8/errors % find . -name \*.log\* | sort > /tmp/8-errs
Note: If it has been a long time since one of the builds finished, the logs may have been automatically compressed with bzip2. In that case, you must use sort | sed 's,\.bz2,,g' instead.
% comm -3 /tmp/8-errs /tmp/8-exp-errs | less
This last command will produce a two-column report. The first column is ports that failed on the control build but not in the experimental patches build; the second column is vice versa. Reasons that the port might be in the first column include:
Port was fixed since the control build was run, or was upgraded to a newer version that is also broken (thus the newer version should appear in the second column)
Port is fixed by the patches in the experimental patches build
Port did not build under the experimental patches build due to a dependency failure
Reasons for a port appearing in the second column include:
Port was broken by the experimental patches
Port was upgraded since the control build and has become broken
Port was broken due to a transient error (e.g., FTP site down, package client error, etc.)
Both columns should be investigated and the reason for the errors understood before committing the experimental patches set. To differentiate between broken by experimental patches and broken by upgrading above, you can do a rebuild of the affected packages under the control branch:
% cd /var/portbuild/i386/8/ports
Note: The following example is obsolete
Note: Be sure to cvs update this tree to the same date as the experimental patches tree.
The following command will set up the control branch for the partial build (old codebase):
% /var/portbuild/scripts/dopackages.8 -noportsvcs -nobuild -novcs -nofinish
The builds must be performed from the packages/All directory. This directory should initially be empty except for the Makefile symlink. If this symlink does not exist, it must be created:
% cd /var/portbuild/i386/8/packages/All % ln -sf ../../Makefile . % make -k -j<#> <list of packages to build>
Note: <#> is the concurrency of the build to attempt. It is usually the sum of the weights listed in /var/portbuild/i386/mlist unless you have a reason to run a heavier or lighter build.
The list of packages to build should be a list of package names (including versions) as they appear in INDEX. The PKGSUFFIX (i.e., .tgz or .tbz) is optional.
This will build only those packages listed as well as all of their dependencies.
You can check the progress of this partial build the same way you would a regular build.
Once all the errors have been resolved, you can commit the package set. After committing, it is customary to send a HEADS UP email to [email protected] and copy [email protected] informing people of the changes. A summary of all changes should also be committed to /usr/ports/CHANGES.
Before following these steps, please coordinate with portmgr.
Note: Due to some generous donations, portmgr is no longer looking for the loan of i386 or amd64 systems. However, we are still interested in borrowing tier-2 systems.
portmgr is still working on characterizing what a node needs to be generally useful.
CPU capacity: anything less than 500MHz is generally not useful for package building.
Note: We are able to adjust the number of jobs dispatched to each machine, and we generally tune the number to use 100% of CPU.
RAM: Less than 2G is not very useful; 8G or more is preferred. We have been tuning to one job per 512M of RAM.
disk: at least 20G is needed for filesystem; 32G is needed for swap. Best performance will be if multiple disks are used, and configured as geom stripes. Performance numbers are also TBA.
Note: Package building will test disk drives to destruction. Be aware of what you are signing up for!
network bandwidth: TBA. However, an 8-job machine has been shown to saturate a cable modem line.
Pick a unique hostname. It does not have to be a publicly resolvable hostname (it can be a name on your internal network).
By default, package building requires the following TCP ports to be accessible: 22 (ssh), 414 (infoseek), and 8649 (ganglia). If these are not accessible, pick others and ensure that an ssh tunnel is set up (see below).
(Note: if you have more than one machine at your site, you will need an individual TCP port for each service on each machine, and thus ssh tunnels will be necessary. As such, you will probably need to configure port forwarding on your firewall.)
Decide if you will be booting natively or via pxeboot. You will find that it is easier to keep up with changes to -current with the latter, especially if you have multiple machines at your site.
Pick a directory to hold ports configuration and chroot subdirectories. It may be best to put it this on its own partition. (Example: /usr2/.)
Note: The filename chroot is a historical remnant.
Create a directory to contain the latest -current source tree and check it out. (Since your machine will likely be asked to build packages for -current, the kernel it runs should be reasonably up-to-date with the bindist that will be exported by our scripts.)
If you are using pxeboot: create a directory to contain the install bits. You will probably want to use a subdirectory of /pxeroot, e.g., /pxeroot/${arch}-${branch}. Export that as DESTDIR.
If you are cross-building, export TARGET_ARCH=${arch}.
Note: The procedure for cross-building ports is not yet defined.
Generate a kernel config file. Include GENERIC (or, if you are using more than 3.5G on i386, PAE).
Required options:
options NULLFS options TMPFS
Suggested options:
options GEOM_CONCAT options GEOM_STRIPE options SHMMAXPGS=65536 options SEMMNI=40 options SEMMNS=240 options SEMUME=40 options SEMMNU=120 options ALT_BREAK_TO_DEBUGGER
For PAE, it is not currently possible to load modules. Therefore, if you are running an architecture that supports Linux emulation, you will need to add:
options COMPAT_LINUX options LINPROCFS
Also for PAE, as of 20110912 you need the following. This needs to be investigated:
nooption NFSD # New Network Filesystem Server options NFSCLIENT # Network Filesystem Client options NFSSERVER # Network Filesystem Server
As root, do the usual build steps, e.g.:
# make -j4 buildworld # make buildkernel KERNCONF=${kernconf} # make installkernel KERNCONF=${kernconf} # make installworld
The install steps use DESTDIR.
Customize files in etc/. Whether you do this on the client itself, or another machine, will depend on whether you are using pxeboot.
If you are using pxeboot: create a subdirectory of ${DESTDIR} called conf/. Create one subdirectory default/etc/, and (if your site will host multiple nodes), subdirectories ${ip-address}/etc/ to contain override files for individual hosts. (You may find it handy to symlink each of those directories to a hostname.) Copy the entire contents of ${DESTDIR}/etc/ to default/etc/; that is where you will edit your files. The by-ip-address etc/ directories will probably only need customized rc.conf files.
In either case, apply the following steps:
Create a ports-${arch} user and group. It can have the '*' password.
Create /home/ports-${arch}/.ssh/ and populate authorized_keys.
Also add the following users:
squid:*:100:100::0:0:User &:/usr/local/squid:/bin/sh ganglia:*:102:102::0:0:User &:/usr/local/ganglia:/bin/sh
Add them to etc/group as well.
Create the appropriate files in etc/.ssh/.
In etc/crontab: add
* * * * * root /var/portbuild/scripts/client-metrics
Create the appropriate etc/fstab. (If you have multiple, different, machines, you will need to put those in the override directories.)
In etc/inetd.conf: add
infoseek stream tcp nowait nobody /var/portbuild/scripts/reportload
You should run the cluster on UTC. If you have not set the clock to UTC:
# cp -p /usr/share/zoneinfo/Etc/UTC etc/localtime
Create the appropriate etc/rc.conf. (If you are using pxeboot, and have multiple, different, machines, you will need to put those in the override directories.)
Recommended entries for physical nodes:
hostname="${hostname}" inetd_enable="YES" linux_enable="YES" nfs_client_enable="YES" ntpd_enable="YES" sendmail_enable="NONE" sshd_enable="YES" sshd_program="/usr/local/sbin/sshd" gmond_enable="YES" squid_enable="YES" squid_chdir="/usr2/squid/logs" squid_pidfile="/usr2/squid/logs/squid.pid"
Required entries for VMWare-based nodes:
vmware_guest_vmmemctl_enable="YES" vmware_guest_guestd_enable="YES"
Recommended entries for VMWare-based nodes:
hostname="" ifconfig_em0="DHCP" fsck_y_enable="YES" inetd_enable="YES" linux_enable="YES" nfs_client_enable="YES" sendmail_enable="NONE" sshd_enable="YES" sshd_program="/usr/local/sbin/sshd" gmond_enable="YES" squid_enable="YES" squid_chdir="/usr2/squid/logs" squid_pidfile="/usr2/squid/logs/squid.pid"
ntpd(8) should not be enabled for VMWare instances.
Also, it may be possible to leave squid disabled by default so as to not have /usr2 persistent (which should save instantiation time.) Work is still ongoing.
Create etc/resolv.conf, if necessary.
Modify etc/sysctl.conf:
9a10,30 > kern.corefile=/usr2/%N.core > kern.sugid_coredump=1 > #debug.witness_ddb=0 > #debug.witness_watch=0 > > # squid needs a lot of fds (leak?) > kern.maxfiles=40000 > kern.maxfilesperproc=30000 > > # Since the NFS root is static we do not need to check frequently for file changes > # This saves >75% of NFS traffic > vfs.nfs.access_cache_timeout=300 > debug.debugger_on_panic=1 > > # For jailing > security.jail.sysvipc_allowed=1 > security.jail.allow_raw_sockets=1 > security.jail.chflags_allowed=1 > security.jail.enforce_statfs=1 > > vfs.lookup_shared=1
If desired, modify etc/syslog.conf to change the logging destinations to @pointyhat.freebsd.org.
Install the following ports:
net/rsync security/openssh-portable (with HPN on) security/sudo sysutils/ganglia-monitor-core (with GMETAD off) www/squid (with SQUID_AUFS on)
There is a WIP to create a meta-port, but it is not yet complete.
Customize files in usr/local/etc/. Whether you do this on the client itself, or another machine, will depend on whether you are using pxeboot.
Note: The trick of using conf override subdirectories is less effective here, because you would need to copy over all subdirectories of usr/. This is an implementation detail of how the pxeboot works.
Apply the following steps:
Modify usr/local/etc/gmond.conf:
21,22c21,22 < name = "unspecified" < owner = "unspecified" --- > name = "${arch} package build cluster" > owner = "[email protected]" 24c24 < url = "unspecified" --- > url = "http://pointyhat.freebsd.org"
If there are machines from more than one cluster in the same multicast domain (basically = LAN) then change the multicast groups to different values (.71, .72, etc).
Create usr/local/etc/rc.d/portbuild.sh, using the appropriate value for scratchdir:
#!/bin/sh # # Configure a package build system post-boot scratchdir=/usr2 ln -sf ${scratchdir}/portbuild /var/ # Identify builds ready for use cd /var/portbuild/arch for i in */builds/*; do if [ -f ${i}/.ready ]; then mkdir /tmp/.setup-${i##*/} fi done # Flag that we are ready to accept jobs touch /tmp/.boot_finished
Modify usr/local/etc/squid/squid.conf:
288,290c288,290 < #auth_param basic children 5 < #auth_param basic realm Squid proxy-caching web server < #auth_param basic credentialsttl 2 hours --- > auth_param basic children 5 > auth_param basic realm Squid proxy-caching web server > auth_param basic credentialsttl 2 hours 611a612 > acl localnet src 127.0.0.0/255.0.0.0 655a657 > http_access allow localnet 2007a2011 > maximum_object_size 400 MB 2828a2838 > negative_ttl 0 minutes
Also, change usr/local to usr2 in cache_dir, access_log, cache_log, cache_store_log, pid_filename, netdb_filename, coredump_dir.
Finally, change the cache_dir storage scheme from ufs to aufs (offers better performance).
Configure ssh: copy etc/ssh to usr/local/etc/ssh and add NoneEnabled yes to sshd_config.
Note: This step is under review.
Create usr/local/etc/sudoers/sudoers.d/portbuild:
# local changes for package building %wheel ALL=(ALL) ALL ports-${arch} ALL=(ALL) NOPASSWD: ALL
Change into the port/package directory you picked above, e.g., cd /usr2.
As root:
# mkdir portbuild # chown ports-${arch}:ports-${arch} portbuild # mkdir pkgbuild # chown ports-${arch}:ports-${arch} pkgbuild # mkdir squid # mkdir squid/cache # mkdir squid/logs # chown -R squid:squid squid
If clients preserve /var/portbuild between boots then they must either preserve their /tmp, or revalidate their available builds at boot time (see the script on the amd64 machines). They must also clean up stale jails from previous builds before creating /tmp/.boot_finished.
Boot the client.
As root, initialize the squid directories:
squid -z
These steps need to be taken by a portmgr acting as ports-${arch} on the server.
If any of the default TCP ports is not available (see above), you will need to create an ssh tunnel for them and include its invocation command in ports-${arch}'s crontab.
Unless you can use the defaults, add an entry to /home/ports-${arch}/.ssh/config to specify the public IP address, TCP port for ssh, username, and any other necessary information.
Create /var/portbuild/${arch}/clients/bindist-${hostname}.tar.
Copy one of the existing ones as a template and unpack it in a temporary directory.
Customize etc/resolv.conf for the local site.
Customize etc/make.conf for FTP fetches for the local site. Note: the nulling-out of MASTER_SITE_BACKUP must be common to all nodes, but the first entry in MASTER_SITE_OVERRIDE should be the nearest local FTP mirror. Example:
.if defined(FETCH_ORIGINAL) MASTER_SITE_BACKUP= .else MASTER_SITE_OVERRIDE= \ ftp://friendly-local-ftp-mirror/pub/FreeBSD/ports/distfiles/${DIST_SUBDIR}/ \ ftp://${BACKUP_FTP_SITE}/pub/FreeBSD/distfiles/${DIST_SUBDIR}/ .endif
tar it up and move it to the right location.
Hint: you will need one of these for each machine; however, if you have multiple machines at one site, you should create a site-specific one (e.g., in /var/portbuild/conf/clients/) and symlink to it.
Create /var/portbuild/${arch}/portbuild-${hostname} using one of the existing ones as a guide. This file contains overrides to /var/portbuild/${arch}/portbuild.conf.
Suggested values:
disconnected=1 http_proxy="http://localhost:3128/" squid_dir=/usr2/squid scratchdir=/usr2/pkgbuild client_user=ports-${arch} sudo_cmd="sudo -H" rsync_gzip=-z infoseek_host=localhost infoseek_port=${tunelled-tcp-port}
Possible other values:
use_md_swap=1 md_size=9g use_zfs=1 scp_cmd="/usr/local/bin/scp" ssh_cmd="/usr/local/bin/ssh"
These steps need to be taken by a portmgr acting as root on pointyhat.
Add the public IP address to /etc/hosts.allow. (Remember, multiple machines can be on the same IP address.)
Add an appropriate data_source entry to /usr/local/etc/gmetad.conf:
data_source "arch/location Package Build Cluster" 30 hostname
You will need to restart gmetad.
These steps need to be taken by a portmgr acting as ports-arch:
Ensure that ssh to the client is working by executing ssh hostname uname -a. The actual command is not important; what is important is to confirm the setup, and also add an entry into known_hosts, once you have confirmed the node's identity.
Populate the client's copy of /var/portbuild/scripts/ by something like /var/portbuild/scripts/dosetupnode arch major latest hostname. Verify that you now have files in that directory.
Test the other TCP ports by executing telnet hostname portnumber. 414 (or its tunnel) should give you a few lines of status information including arch and osversion; 8649 should give you an XML response from ganglia.
This step needs to be taken by a portmgr acting as root:
Tell qmanager about the node. Example:
python path/qmanager/qclient add name=uniquename arch=arch osversion=osversion numcpus=number haszfs=0 online=1 domain=domain primarypool=package pools="package all" maxjobs=1 acl="ports-arch,deny_all"
Finally, again as portmgr acting as ports-arch:
Once you are sure that the client is working, tell pollmachine about it by adding it to /var/portbuild/${arch}/mlist.
When a new branch is created, some work needs to be done to specify that the previous branch is no longer equivalent to HEAD.
Edit /var/portbuild/conf/server.conf with the following changes:
Add new-branch to SRC_BRANCHES.
For what was previously head, change SRC_BRANCH_branch_SUBDIR to releng/branch.0 (literal zero).
Add SRC_BRANCH_new-branch_SUBDIR =head.
Run /var/portbuild/updatesnap manually.
Note: Again, as ports-arch:
For each branch that will be supported, do the following:
Kick-start the build for the branch with:
build create arch branch
When an old branch goes out of support, there are some things to garbage-collect.
Edit /var/portbuild/conf/server.conf with the following changes:
Delete old-branch from SRC_BRANCHES.
Delete SRC_BRANCH_old-branch_SUBDIR= whatever
umount a/snap/src-old-branch/src; umount a/snap/src-old-branch; zfs destroy -r a/snap/src-old-branch
You will probably find that the following files and symlinks in /var/portbuild/errorlogs/ can be removed:
Files named *-old_branch-failure.html
Files named buildlogs_*-old_branch-*-logs.txt
Symlinks named *-old_branch-previous*
Symlinks named *-old_branch-latest*
As of 2011, the philosophy of package building is to build packages based on the earliest supported release of each branch. e.g.: if on RELENG-8, the following releases are supported: 8.1, 8.2, 8.3; then packages-8-stable should be built from 8.1.
As releases go End-Of-Life (see chart), a full (not incremental!) package build should be done and uploaded.
The procedure is as follows:
Edit /var/portbuild/conf/server.conf with the following changes:
Change the value of SRC_BRANCH_branch_SUBDIR to releng/branch.N where N is the newest 'oldest' release for that branch.
Run /var/portbuild/updatesnap manually.
Run dopackages with -nobuild.
Follow the setup procedure.
Now you can run dopackages without -nobuild.
Note: The initial steps need to be done using sudo.
Create a new ports-arch user and group.
mkdir /var/portbuild/arch
Create a new zfs filesystem:
# zfs create -o mountpoint=/a/portbuild/arch a/portbuild/arch
# chown ports-arch:portbuild /var/portbuild/arch; # chmod 775 /var/portbuild/arch; # cd /var/portbuild/arch
Create the .ssh directory.
Note: The next steps are most easily done as user ports-arch.
Create an archive directory for buildlogs and errorlogs under archive/.
For each branch that will be supported, do the following:
Kick-start the build for the branch with
# build create arch branch
If you are going to store your historical buildlogs and errorlogs on your head node's hard drive, you may skip this step. Otherwise:
Create an external directory and link to it:
Example 9. Creating and linking an external archive directory
# mkdir /dumpster/pointyhat/arch/archive # ln -s /dumpster/pointyhat/arch/archive archive
Note: (Historical note that only applied to the original pointyhat.FreeBSD.org installation)
It is possible that /dumpster/pointyhat will not have enough space. In that case, create the archive directory as /dumpster/pointyhat/arch/archive and symlink to that.
Populate clients as usual.
Create a fresh portbuild.conf file from one of the ones for another architecture.
Create customized portbuild.machinename.conf files as appropriate.
# cd .ssh && ssh-keygen
If desired, edit the .ssh/config file for convenience in using ssh.
If you need to create any tunnels:
Make a private configuration directory:
# mkdir /var/portbuild/conf/arch
In that directory: create any dotunnel.* scripts needed.
Note: Once again using sudo:
Add arch to SUPPORTED_ARCHS in /var/portbuild/conf/server.conf.
Add the arch directory to /var/portbuild/scripts/zbackup and /var/portbuild/scripts/zexpire.
Note: One last time using sudo:
Add an appropriate arch entry for /var/portbuild/scripts/dologs to the root crontab. (This is a hack and should go away.)
Note: Again using sudo:
Tell qmanager about the arch:
python path/qmanager/qclient add_acl name=ports-arch uidlist=ports-arch gidlist=portbuild sense=1
For each branch that will be supported, do the following:
Please talk to Mark Linimon before making any changes to this section.
Install FreeBSD.
Create a user to own the portbuild repository, such as portbuild. It should have the '*' password.
Export that value for a later initialization step:
# export PORTBUILD_USER=portbuild
Add the following to /boot/loader.conf:
console="vidconsole,comconsole"
You should run the cluster on UTC. If you have not set the clock to UTC:
# cp -p /usr/share/zoneinfo/Etc/UTC /etc/localtime
Create the appropriate /etc/rc.conf.
Required entries:
hostname="${hostname}" sshd_enable="YES"
Recommended entries:
background_fsck="NO" clear_tmp_enable="YES" dumpdev="AUTO" fsck_y_enable="YES" apache22_enable="YES" apache_flags="" apache_pidfile="/var/run/httpd.pid" gmetad_enable="YES" gmond_enable="YES" inetd_enable="YES" # XXX MCL try these instead. inetd_flags="-R 10000 -l -w" mountd_enable="YES" nfs_server_enable="YES" nfs_server_flags="-u -t -n 12" nfs_remote_port_only="YES" ntpd_enable="YES" rpcbind_enable="YES" rpc_lockd_enable="NO" rpc_statd_enable="YES" sendmail_enable="NONE" smartd_enable="YES" zfs_enable="YES"
Create /etc/resolv.conf, if necessary.
Create the appropriate files in /etc/ssh/.
Add the following to /etc/sysctl.conf:
kern.maxfiles=40000 kern.maxfilesperproc=38000 sysctl vfs.usermount=1 sysctl vfs.zfs.super_owner=1
Make sure the following change is made to /etc/ttys:
ttyu0 "/usr/libexec/getty std.9600" vt100 on secure
You should be able to install from the most recent release using only the default kernel configuration.
The following ports (or their latest successors) are required:
databases/py-sqlite3 databases/py-sqlalchemy (only SQLITE is needed) devel/git (WITH_SVN) devel/py-configobj devel/py-setuptools devel/subversion net/nc net/rsync sysutils/ganglia-monitor-core (with GMETAD off) sysutils/ganglia-webfrontend (compile with -DWITHOUT_X11) www/apache22 (with EXT_FILTER)
Expect those to bring in, among others:
databases/sqlite3 lang/perl-5.14 (or successor) lang/python27 (or sucessor)
The following ports (or their latest successors) are strongly suggested:
devel/ccache mail/postfix net/isc-dhcp41-server ports-mgmt/pkg ports-mgmt/portaudit ports-mgmt/portmaster security/sudo shells/bash shells/zsh sysutils/screen
The following ports (or their latest successors) are handy:
benchmarks/bonnie++ ports-mgmt/pkg_tree sysutils/dmidecode sysutils/smartmontools sysutils/zfs-stats
The following steps need to be done as euid root.
Pick a zfs volume name and export it. We have used a so far to date.
# export ZFS_VOLUME=a
Pick a mountpoint and export it. We have used /a so far to date.
# export ZFS_MOUNTPOINT=/a
Create the zfs volume and mount it.
Example 10. Creating a zfs volume for portbuild
# zpool create ${ZFS_VOLUME} mirror da1 da2 mirror da3 da4 mirror da5 da6 mirror da7 da8
Note: We will define a zfs permission set below, so that the portbuild user may administer this volume without having to have root privileges.
Select an svn repository and export it. See the FreeBSD Handbook for the currently supported list.
# export VCS_REPOSITORY=svn://svn0.us-east.FreeBSD.org
Obtain a copy of the kickstart script into a temporary directory. (You will not need to keep this directory later.)
# mkdir -p /home/portbuild/tmp # svn checkout ${VCS_REPOSITORY}/base/projects/portbuild/tools /home/portbuild/tmp
Run the kickstart script:
# sh /home/portbuild/tmp/mkportbuild
This will accomplish all the following 5 steps:
Create the portbuild directory:
# mkdir -p ${ZFS_MOUNTPOINT}/portbuild
Create and mount a new zfs filesystem on it:
zfs create -o mountpoint=${ZFS_MOUNTPOINT}/portbuild ${ZFS_VOLUME}/portbuild
Set up the directory:
# chown ${PORTBUILD_USER}:${PORTBUILD_USER} ${ZFS_MOUNTPOINT}/portbuild # chmod 775 ${ZFS_MOUNTPOINT}/portbuild # ln -sf ${ZFS_MOUNTPOINT}/portbuild /var/portbuild
Note: The ln is necessary due to a number of hardcoded paths. This is a bug.
set up the repository:
% svn checkout ${VCS_REPOSITORY}/base/projects/portbuild ${ZFS_MOUNTPOINT}/portbuild
Set up the zfs permission set:
# ${ZFS_MOUNTPOINT}/tools/zfsadmin
Configure how build slaves will talk to your server by making the following changes to /a/portbuild/conf/client.conf:
Set CLIENT_NFS_MASTER to wherever your build slaves will PXE boot from. (Possibly, the hostname of your server.)
Set CLIENT_BACKUP_FTP_SITE to a backup site for FTP fetches; again, possibly the hostname of your server.
Set CLIENT_UPLOAD_HOST to where completed packages will be uploaded.
Most of the other default values should be fine.
Most of the default values in /a/portbuild/conf/common.conf should be fine. This file holds definitions used by both the server and all its clients.
Configure the server by making the following changes to /a/portbuild/conf/server.conf:
Set SUPPORTED_ARCHS to the list of architectures you wish to build packages for.
For each source branch you will be building for, set SRC_BRANCHES and SRC_BRANCH_branch_SUBDIR as detailed in Section 14.1. You should not need to change SRC_BRANCHES_PATTERN.
Set ZFS_VOLUME and ZFS_MOUNTPOINT to whatever you chose above.
Set UPLOAD_DIRECTORY, UPLOAD_TARGET, and UPLOAD_USER as appropriate for your site.
Set VCS_REPOSITORY to whatever you chose above.
Set MASTER_URL to the http URL of your server. This will be stamped into the package build logs and the indices thereof.
Most of the other default values should be fine.
Copy the following files from /var/portbuild/etc/rc.d/ to /usr/local/etc/rc.d/:
buildproxy pollmachine qmanager
As root, start each one of them. You may find it handy to start each under screen for debugging purposes.
Initialize the qmanager database's acl list:
Note: This should now be automatically done for you by the first build command.
# python /a/portbuild/qmanager/qclient add_acl name=deny_all uidlist= gidlist= sense=0
As the portbuild user, run the following commands manually to create the src and ports repositories, respectively:
% /a/portbuild/scripts/updatesnap.ports % /a/portbuild/scripts/updatesnap
These will be periodically run from the portbuild crontab, which you will install below.
Configure /usr/local/etc/apache22/httpd.conf as appropriate for your site.
Copy /var/portbuild/conf/apache.conf to the appropriate Includes/ subdirectory, e.g., /usr/local/etc/apache22/Includes/portbuild.conf. Configure it as appropriate for your site.
Install /var/portbuild/crontabs/root as the root crontab via crontab -e.
Install /var/portbuild/crontabs/portbuild as the portbuild crontab via crontab -u portbuild -e. If you do not support all the archs listed there, make sure to comment out the appropriate dologs entries.
If your build slaves will be pxebooted, make sure to enable the tftp entries in /etc/inetd.conf.
Configure mail by doing the following:
newaliases.
For each architecture, follow the steps in Section 17.2.
At some point, you will probably find it handy to append the following to the PATH definition for the portbuild user:
/a/portbuild/scripts:/a/portbuild/tools
You should now be ready to build packages.
Note: The following section is particular to freebsd.org and is somewhat obsolete.
When a machine has a disk failure (e.g., panics due to read errors, etc), then we should do the following steps:
Note the time and failure mode (e.g., paste in the relevant console output) in /var/portbuild/${arch}/reboots
For i386 gohan clients, scrub the disk by touching /SCRUB in the nfsroot (e.g., /a/nfs/8.dir1/SCRUB) and rebooting. This will dd if=/dev/zero of=/dev/ad0 and force the drive to remap any bad sectors it finds, if it has enough spares left. This is a temporary measure to extend the lifetime of a drive that is on the way out.
Note: For the i386 blade systems another signal of a failing disk seems to be that the blade will completely hang and be unresponsive to either console break, or even NMI.
For other build systems that do not newfs their disk at boot (e.g., amd64 systems) this step has to be skipped.
If the problem recurs, then the disk is probably toast. Take the machine out of mlist and (for ata disks) run smartctl on the drive:
smartctl -t long /dev/ad0
It will take about 1/2 hour:
gohan51# smartctl -t long /dev/ad0 smartctl version 5.38 [i386-portbld-freebsd8.0] Copyright (C) 2002-8 Bruce Allen Home page is http://smartmontools.sourceforge.net/ === START OF OFFLINE IMMEDIATE AND SELF-TEST SECTION === Sending command: "Execute SMART Extended self-test routine immediately in off-line mode". Drive command "Execute SMART Extended self-test routine immediately in off-line mode" successful. Testing has begun. Please wait 31 minutes for test to complete. Test will complete after Fri Jul 4 03:59:56 2008 Use smartctl -X to abort test.
Then smartctl -a /dev/ad0 shows the status after it finishes:
# SMART Self-test log structure revision number 1 # Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error # 1 Extended offline Completed: read failure 80% 15252 319286
It will also display other data including a log of previous drive errors. It is possible for the drive to show previous DMA errors without failing the self-test though (because of sector remapping).
When a disk has failed, please inform the cluster administrators so we can try to get it replaced.
