Subject: LU-3689 tests: Support ZFS in large-lun.sh and run_llverdev
X-Git-Tag: 2.5.52~43
X-Git-Url: https://git.whamcloud.com/?p=fs%2Flustre-release.git;a=commitdiff_plain;h=c0a57501d5610353ee4b1cc841ef7de2a92300bd

LU-3689 tests: Support ZFS in large-lun.sh and run_llverdev

This adds support to "check" zfs and run llrevfs against zfs backed
nodes.  This fixes some regressions added by LU-3264, specifically
that the stop function also exports the zfs pool.

The zfs "check" is really a non-entity since there is no functional
zfs fsck at this time.
