November 23, 20232 yr I recently set up a drive as zfs for zfs snapshots. That was working fine till this morning. I am confused by the messaging because the drive seems to be ok but unraid doesn’t think it is. How do I handle? I ran smart check and no errors Edited November 23, 20232 yr by andyd
November 23, 20232 yr Community Expert If Unraid was unable to read/write from the drive it'll have disabled it whether the drive itself is actually good. Probably was a communication error with the drive so check power and data cabling, or for a failing HBA if one is in use.
November 23, 20232 yr Author All drives are on a sas card. I would expect other drives to have issues as well if it was the card. does it make sense to turn off / on server to see if it corrects itself?
November 23, 20232 yr Community Expert Solution Once disabled it'll stay disabled even afrer a reboot, only a rebuild onto itself (once you've confirmed the drive and cabling are good) will get you back to normal. https://docs.unraid.net/unraid-os/manual/storage-management/#rebuilding-a-drive-onto-itself Edited November 23, 20232 yr by Kilrah
November 27, 20232 yr Author Ok thanks - I did the steps without going into maintenance mode and drive is fine again
