Olaf Faaland	379ca9cf2b	Multi-modifier protection (MMP) ... 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.

Brian Behlendorf	8c54ddd33a	Enable additional test cases ... Enable additional test cases, in most cases this required a few minor modifications to the test scripts. In a few cases a real bug was uncovered and fixed. And in a handful of cases where pools are layered on pools the test case will be skipped until this is supported. Details below for each test case. * zpool_add_004_pos - Skip test on Linux until adding zvols to pools is fully supported and deadlock free. * zpool_add_005_pos.ksh - Skip dumpadm portion of the test which isn't relevant for Linux. The find_vfstab_dev, find_mnttab_dev, and save_dump_dev functions were updated accordingly for Linux. Add O_EXCL to the in-use check to prevent the -f (force) option from working for mounted filesystems and improve the resulting error. * zpool_add_006_pos - Update test case such that it doesn't depend on nested pools. Switch to truncate from mkfile to reduce space requirements and speed up the test case. * zpool_clear_001_pos - Speed up test case by filling filesystem to 25% capacity. * zpool_create_002_pos, zpool_create_004_pos - Use sparse files for file vdevs in order to avoid increasing the partition size. * zpool_create_006_pos - 6ba1ce9 allows raidz+mirror configs with similar redundancy. Updating the valid_args and forced_args cases. * zpool_create_008_pos - Disable overlapping partition portion. * zpool_create_011_neg - Fix to correctly create the extra partition. Modified zpool_vdev.c to use fstat64_blk() wrapper which includes the st_size even for block devices. * zpool_create_012_neg - Updated to properly find swap devices. * zpool_create_014_neg, zpool_create_015_neg - Updated to use swap_setup() and swap_cleanup() wrappers which do the right thing on Linux and Illumos. Removed '-n' option which succeeds under Linux due to differences in the in-use checks. * zpool_create_016_pos.ksh - Skipped test case isn't useful. * zpool_create_020_pos - Added missing / to cleanup() function. Remove cache file prior to test to ensure a clean environment and avoid false positives. * zpool_destroy_001_pos - Removed test case which creates a pool on a zvol. This is more likely to deadlock under Linux and has never been completely supported on any platform. * zpool_destroy_002_pos - 'zpool destroy -f' is unsupported on Linux. Mount point must not be busy in order to unmount them. * zfs_destroy_001_pos - Handle EBUSY error which can occur with volumes when racing with udev. * zpool_expand_001_pos, zpool_expand_003_neg - Skip test on Linux until adding zvols to pools is fully supported and deadlock free. The test could be modified to use loop-back devices but it would be preferable to use the test case as is for improved coverage. * zpool_export_004_pos - Updated test case to such that it doesn't depend on nested pools. Normal file vdev under /var/tmp are fine. * zpool_import_all_001_pos - Updated to skip partition 1, which is known as slice 2, on Illumos. This prevents overwriting the default TESTPOOL which was causing the failure. * zpool_import_002_pos, zpool_import_012_pos - No changes needed. * zpool_remove_003_pos - No changes needed * zpool_upgrade_002_pos, zpool_upgrade_004_pos - Root cause addressed by upstream OpenZFS commit 3b7f360. * zpool_upgrade_007_pos - Disabled in test case due to known failure. Opened issue https://github.com/zfsonlinux/zfs/issues/6112 * zvol_misc_002_pos - Updated to to use ext2. * zvol_misc_001_neg, zvol_misc_003_neg, zvol_misc_004_pos, zvol_misc_005_neg, zvol_misc_006_pos - Moved to skip list, these test case could be updated to use Linux's crash dump facility. * zvol_swap_* - Updated to use swap_setup/swap_cleanup helpers. File creation switched from /tmp to /var/tmp. Enabled minimal useful tests for Linux, skip test cases which aren't applicable.
