Hi, we had a server that lost connection to fiber attached disk array where
data luns were housed, due to 3510 power fault. After connection restored alot
of the zpool status had these permanent errors listed as per below. I check the
files in question and as far as I could see they were present and ok. I ran a
zpool scrub against other zpools and they came back with no errors and the list
of permanent errors has cleared. Does this mean the files were ok and zfs just
got a bit confused with the dissappearing and re-appearing lun's? or does the
scrub just reset the list of errors, and there could still be data loss? This
is the last one in progress, it will take a while to finish... I also check the
contents of some logs and text files that were also mentioned previously and
they looked ok before the scrub. Do I need to chksum the orig and backed up
files?
root@# zpool status -xv
pool: APP1
state: ONLINE
status: One or more devices has experienced an error resulting in data
corruption. Applications may be affected.
action: Restore the file in question if possible. Otherwise restore the
entire pool from backup.
