Hi, I would like to ask for advice. We've had a UPS failure in the server room and one of our boxes couldn't import zfs pool named spool after the box rebooted. The error message was:
# zpool import spool
cannot import 'spool': I/O error
Destroy and re-create the pool from
a backup source.
# zpool import -F spool
cannot import 'spool': I/O error
Destroy and re-create the pool from
a backup source.
# zpool import -fF spool
cannot import 'spool': I/O error
Destroy and re-create the pool from
a backup source.
Running zpool import -fFX at least started and it now runs more than 60 hours on this 8x4TB striped, mirrored (raid10) pool . The documentation states the extreme rewind import (import -X) performs a full traversal of all blocks in the pool for verification. I'm also monitoring the disk data reads with iostat, and it shows 11.5TB total reads per disk at the moment. Is there any method to discover about the status for the recovery process?
Any help appriciated.
Thanks in advance.
