September 3, 2025Sep 3 At some point over night, while the new parity drive was rebuilding, there was a drive failure. Tried to roll back to the old parity drive, but can't get the array started, because the array wants the new parity drive. How can I get the array started with the old parity drive to rebuild the failed drive?

September 10, 2025Sep 10 Community Expert SMART looks fine for disk2, run an extended SMART test on it and post the results.

September 12, 2025Sep 12 Community Expert Solution Disk2 is OK, at least for now, I would recommend replacing disk2 cables to rule that out, then doing a new config (tools - new config) and trying again to sync the new parity. Any errors, post new diags before rebooting.
