[OmniOS-discuss] Corrupted file recovery and restoring pool to ONLINE

[Schweiss, Chip]

To get back to an online state you need to detach the offline disk:

zpool detach B-034 c10t50000C0F0132772Ed0s0

If the corrupted file is in any snapshots those snapshots will have to be
destroyed to stop it from being found as a corruption during a scrub.
