Is it necessary regular scrub for zfs back-ends?
by Arman Khalatyan
Hello,
I found that in the LUG2015 talk by Gabriele Paciucci states that:
"Resilvering and scrubbing are autotuned by the ZFS I/O scheduler"
When I trigger
lctl lfsck_start -M zaip-MDT0000 --all
the zpool status does not show the scrub progress.
As I understood from the Lustre Manual the lfsck_start fixes the lustre
relevant part but not zfs,
Should I schedule the zpool scrub in order to avoid blocks corruption?
Thanks,
Arman.
