      ZTS: Fix zpool_expand_001_pos · b3d0568c
      Tony Hutter 创作于
      `zpool_expand_001_pos` was often failing due to not seeing autoexpand
      commands in the `zpool history`.  During testing, I found this to be
      unreliable (sometimes the "online" wouldn't appear in `zpool history`)
      and unnecessary, as we could simply check that the pool increased in
      This commit revamps the test to check for the expanded pool size
      and corresponding new free space.

      Add support for per dataset zil stats and use wmsum counters · fb087146
      ixhamza 创作于
      ZIL kstats are reported in an inclusive way, i.e., same counters are
      shared to capture all the activities happening in zil. Added support
      to report zil stats for every datset individually by combining them
      with already exposed dataset kstats.
      Wmsum uses per cpu counters and provide less overhead as compared
      to atomic operations. Updated zil kstats to replace wmsum counters
      to avoid atomic operations.

      Fix scrub resume from newly created hole · 33dba8c7
      Alexander Motin 创作于
      It may happen that scan bookmark points to a block that was turned
      into a part of a big hole.  In such case dsl_scan_visitbp() may skip
      it and dsl_scan_check_resume() will not be called for it.  As result
      new scan suspend won't be possible until the end of the object, that
      may take hours if the object is a multi-terabyte ZVOL on a slow HDD
      pool, stretching TXG to all that time, creating all sorts of problems.
      This patch changes the resume condition to any greater or equal block,
      so even if we miss the bookmarked block, the next one we find will
      delete the bookmark, allowing new suspend.

      Avoid memory copy when verifying raidz/draid parity · 74230a5b
      Alexander Motin 创作于
      Before this change for every valid parity column raidz_parity_verify()
      allocated new buffer and copied there existing data, then recalculated
      the parity and compared the result with the copy.  This patch removes
      the memory copy, simply swapping original buffer pointers with newly
      allocated empty ones for parity recalculation and comparison. Original
      buffers with potentially incorrect parity data are then just freed,
      while new recalculated ones are used for repair.
      On a pool of 12 4-wide raidz vdevs, storing 1.5TB of 16MB blocks, this
      change reduces memory traffic during scrub by 17% and total unhalted
      CPU time by 25%.

      Avoid memory copies during mirror scrub · 1ac7d194
      Alexander Motin 创作于
      Issuing several scrub reads for a block we may use the parent ZIO
      buffer for one of child ZIOs.  If that read complete successfully,
      then we won't need to copy the data explicitly.  If block has only
      one copy (typical for root vdev, which is also a mirror inside),
      then we never need to copy -- succeed or fail as-is.  Previous
      code also copied data from buffer of every successfully completed
      child ZIO, but that just does not make any sense.
      On healthy N-wide mirror this saves all N+1 (or even more in case
      of ditto blocks) memory copies for each scrubbed block, allowing
      CPU to focus mostly on check-summing.  For other vdev types it
      should save one memory copy per block copy at root vdev.
