Issue: https://www.illumos.org/issues/4897 Review: http://reviews.csiden.org/r/35/
L2ARC vdev space usage statistics are calculated as the delta between the maximum and minimum vdev offset ever written to by the L2ARC fill thread, but do not inform the user of how much space in between these two offsets is actually taken up by cached buffers. This fix changes that so that vdev space usage stats on L2ARC devices accurately track the volume of buffers stored on them, allowing users to see the exact L2ARC usage in "zpool iostat -v". -- Saso _______________________________________________ developer mailing list [email protected] http://lists.open-zfs.org/mailman/listinfo/developer
