* New service that waits on zvol links to be createdPavel Zakharov2019-07-172-1/+22
| | | | | | | | | | | | | | | | The zfs-volume-wait.service scans existing zvols and waits for their links under /dev to be created. Any service that depends on zvol links to be there should add a dependency on zfs-volumes.target. By default, this target is not enabled.

* Update build system and packagingBrian Behlendorf2018-05-291-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Minimal changes required to integrate the SPL sources in to the ZFS repository build infrastructure and packaging. Build system and packaging: * Renamed SPL_* autoconf m4 macros to ZFS_*. * Removed redundant SPL_* autoconf m4 macros. * Updated the RPM spec files to remove SPL package dependency. * The zfs package obsoletes the spl package, and the zfs-kmod package obsoletes the spl-kmod package. * The zfs-kmod-devel* packages were updated to add compatibility symlinks under /usr/src/spl-x.y.z until all dependent packages can be updated. They will be removed in a future release. * Updated copy-builtin script for in-kernel builds. * Updated DKMS package to include the spl.ko. * Updated stale AUTHORS file to include all contributors. * Updated stale COPYRIGHT and included the SPL as an exception. * Renamed README.markdown to README.md * Renamed OPENSOLARIS.LICENSE to LICENSE. * Renamed DISCLAIMER to NOTICE. Required code changes: * Removed redundant HAVE_SPL macro. * Removed _BOOT from nvpairs since it doesn't apply for Linux. * Initial header cleanup (removal of empty headers, refactoring). * Remove SPL repository clone/build from zimport.sh. * Use of DEFINE_RATELIMIT_STATE and DEFINE_SPINLOCK removed due to build issues when forcing C99 compilation. * Replaced legacy ACCESS_ONCE with READ_ONCE. * Include needed headers for `current` and `EXPORT_SYMBOL`.

* Extend deadman logicBrian Behlendorf2018-01-251-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The intent of this patch is extend the existing deadman code such that it's flexible enough to be used by both ztest and on production systems. The proposed changes include: * Added a new `zfs_deadman_failmode` module option which is used to dynamically control the behavior of the deadman. It's loosely modeled after, but independant from, the pool failmode property. It can be set to wait, continue, or panic. * wait - Wait for the "hung" I/O (default) * continue - Attempt to recover from a "hung" I/O * panic - Panic the system * Added a new `zfs_deadman_ziotime_ms` module option which is analogous to `zfs_deadman_synctime_ms` except instead of applying to a pool TXG sync it applies to zio_wait(). A default value of 300s is used to define a "hung" zio. * The ztest deadman thread has been re-enabled by default, aligned with the upstream OpenZFS code, and then extended to terminate the process when it takes significantly longer to complete than expected. * The -G option was added to ztest to print the internal debug log when a fatal error is encountered. This same option was previously added to zdb in commit fa603f82. Update zloop.sh to unconditionally pass -G to obtain additional debugging. * The FM_EREPORT_ZFS_DELAY event which was previously posted when the deadman detect a "hung" pool has been replaced by a new dedicated FM_EREPORT_ZFS_DEADMAN event. * The proposed recovery logic attempts to restart a "hung" zio by calling zio_interrupt() on any outstanding leaf zios. We may want to further restrict this to zios in either the ZIO_STAGE_VDEV_IO_START or ZIO_STAGE_VDEV_IO_DONE stages. Calling zio_interrupt() is expected to only be useful for cases when an IO has been submitted to the physical device but for some reasonable the completion callback hasn't been called by the lower layers. This shouldn't be possible but has been observed and may be caused by kernel/driver bugs. * The 'zfs_deadman_synctime_ms' default value was reduced from 1000s to 600s. * Depending on how ztest fails there may be no cache file to move. This should not be considered fatal, collect the logs which are available and carry on. * Add deadman test cases for spa_deadman() and zio_wait(). * Increase default zfs_deadman_checktime_ms to 60s.

* Retire legacy test infrastructureBrian Behlendorf2017-08-153-243/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Removed zpios kmod, utility, headers and man page. * Removed unused scripts zpios-profile/*, zpios-test/*, zpool-config/*, smb.sh, zpios-sanity.sh, zpios-survey.sh, zpios.sh, and zpool-create.sh. * Removed zfs-script-config.sh.in. When building 'make' generates a common.sh with in-tree path information from the common.sh.in template. This file and sourced by the test scripts and used for in-tree testing, it is not included in the packages. When building packages 'make install' uses the same template to create a new common.sh which is appropriate for the packaging. * Removed unused functions/variables from scripts/common.sh.in. Only minimal path information and configuration environment variables remain. * Removed unused scripts from scripts/ directory. * Remaining shell scripts in the scripts directory updated to cleanly pass shellcheck and added to checked scripts. * Renamed tests/test-runner/cmd/ to tests/test-runner/bin/ to match install location name. * Removed last traces of the --enable-debug-dmu-tx configure options which was retired some time ago.

* Multi-modifier protection (MMP)Olaf Faaland2017-07-131-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add multihost=on|off pool property to control MMP. When enabled a new thread writes uberblocks to the last slot in each label, at a set frequency, to indicate to other hosts the pool is actively imported. These uberblocks are the last synced uberblock with an updated timestamp. Property defaults to off. During tryimport, find the "best" uberblock (newest txg and timestamp) repeatedly, checking for change in the found uberblock. Include the results of the activity test in the config returned by tryimport. These results are reported to user in "zpool import". Allow the user to control the period between MMP writes, and the duration of the activity test on import, via a new module parameter zfs_multihost_interval. The period is specified in milliseconds. The activity test duration is calculated from this value, and from the mmp_delay in the "best" uberblock found initially. Add a kstat interface to export statistics about Multiple Modifier Protection (MMP) updates. Include the last synced txg number, the timestamp, the delay since the last MMP update, the VDEV GUID, the VDEV label that received the last MMP update, and the VDEV path. Abbreviated output below. $ cat /proc/spl/kstat/zfs/mypool/multihost 31 0 0x01 10 880 105092382393521 105144180101111 txg timestamp mmp_delay vdev_guid vdev_label vdev_path 20468 261337 250274925 68396651780 3 /dev/sda 20468 261339 252023374 6267402363293 1 /dev/sdc 20468 261340 252000858 6698080955233 1 /dev/sdx 20468 261341 251980635 783892869810 2 /dev/sdy 20468 261342 253385953 8923255792467 3 /dev/sdd 20468 261344 253336622 042125143176 0 /dev/sdab 20468 261345 253310522 1200778101278 2 /dev/sde 20468 261346 253286429 0950576198362 2 /dev/sdt 20468 261347 253261545 96209817917 3 /dev/sds 20468 261349 253238188 8555725937673 3 /dev/sdb Add a new tunable zfs_multihost_history to specify the number of MMP updates to store history for. By default it is set to zero meaning that no MMP statistics are stored. When using ztest to generate activity, for automated tests of the MMP function, some test functions interfere with the test. For example, the pool is exported to run zdb and then imported again. Add a new ztest function, "-M", to alter ztest behavior to prevent this. Add new tests to verify the new functionality.

* SIMD implementation of vdev_raidz generate and reconstruct routinesGvozden Neskovic2016-06-212-1/+98
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a new implementation of RAIDZ1/2/3 routines using x86_64 scalar, SSE, and AVX2 instruction sets. Included are 3 parity generation routines (P, PQ, and PQR) and 7 reconstruction routines, for all RAIDZ level. On module load, a quick benchmark of supported routines will select the fastest for each operation and they will be used at runtime. Original implementation is still present and can be selected via module parameter. Patch contains: - specialized gen/rec routines for all RAIDZ levels, - new scalar raidz implementation (unrolled), - two x86_64 SIMD implementations (SSE and AVX2 instructions sets), - fastest routines selected on module load (benchmark). - cmd/raidz_test - verify and benchmark all implementations - added raidz_test to the ZFS Test Suite New zfs module parameters: - zfs_vdev_raidz_impl (str): selects the implementation to use. On module load, the parameter will only accept first 3 options, and the other implementations can be set once module is finished loading. Possible values for this option are: "fastest" - use the fastest math available "original" - use the original raidz code "scalar" - new scalar impl "sse" - new SSE impl if available "avx2" - new AVX2 impl if available See contents of `/sys/module/zfs/parameters/zfs_vdev_raidz_impl` to get the list of supported values. If an implementation is not supported on the system, it will not be shown. Currently selected option is enclosed in `[]`.

* Increase default user space stack sizeBrian Behlendorf2016-01-131-4/+3
| | | | | | | | | | | | | | | | | | | | Under RHEL6/CentOS6 the default stack size must be increased to 32K to prevent overflowing the stack when running ztest. This isn't an issue for other distributions due to either the version of pthreads or perhaps the compiler. Doubling the stack size resolves the issue safely for all distribution and leaves us some headroom. $ sudo -E ztest -V -T 300 -f /var/tmp/ 5 vdevs, 7 datasets, 23 threads, 300 seconds... loading space map for vdev 0 of 1, metaslab 0 of 30 ... ... loading space map for vdev 0 of 1, metaslab 14 of 30 ... child died with signal 11 Exited ztest with error 3 Signed-off-by: Brian Behlendorf <[email protected]> Closes #4215

* Add large block support to zpios(1) benchmarkDon Brady2015-09-221-2/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As part of the large block support effort, it makes sense to add support for large blocks to **zpios(1)**. The specifying of a zfs block size for zpios is optional and will default to 128K if the block size is not specified. `zpios ... -S size | --blocksize size ...` This will use *size* ZFS blocks for each test, specified as a comma delimited list with an optional unit suffix. The supported range is powers of two from 128K through 16M.

* Make user stack limit configurableBrian Behlendorf2014-09-301-0/+16
| | | | | | | | | | | | | | | | | To aid in detecting and debugging stack overflow issues make the user space stack limit configurable via a new ZFS_STACK_SIZE environment variable. The value assigned to ZFS_STACK_SIZE will be used as the default stack size in bytes. Because this is mainly useful as a debugging aid in conjunction with ztest the stack limit is disabled by default. See the ztest(1) man page for additional details on using the ZFS_STACK_SIZE environment variable.

* Add cstyle.pl utility and cstyle.1 man pageBrian Behlendorf2013-10-302-1/+168
| | | | | | | | | | | | | | | | | | | | | | | | Cstyle is the C source style checker used by Illumos. Since the original ZFS source was written using these style guidelines they must also be followed by ZoL for consistency. The checker has been added to the scripts directory and may be run on a per file basis. New patches should be careful to avoid introducing new style warnings. Additionally, the 'checkstyle' target has been added to the top level Makefile and can be used to check the entire source tree. While Zol has historically attempted to follow the SunOS style guide the lack of a rigorous style checker has allowed various warning to be introduced. Currently there are 2211 reported style violations and we want to gradually eliminate these from the tree. Note the cstyle.1 man page is provided under man/man1/cstyle.1 but since it is a developer utility it is not installed along with the other man pages.
