Parity Disk Disabled - write errors

[KablammoNick]

A few days ago we lost mains power to the house, and the UPS I had my server connected to didn't seem to keep anything running long enough for a safe shutdown.

 

I'm not sure if this is related, as I hadn't had any alerts prior, but I then noticed that the parity device was disabled. Couldn't see anything in the logs (hence thinking it might have been pre-power loss), and the only troubleshooting threads I could find said to remove from array, restart, re-add, and rebuild parity.

It started this fine, got mostly through and:

 

 

SMART tests all pass - had started the RMA process as it's an IronWolf Pro drive <12 months old, but wanted to eliminate whether it was anything else in the system (eg controller or power).

 

Ran SeaTools off USB, long SMART test all passed.

 

Tried remove/add/rebuild again but this time caught it in the log when I was sitting next to it and heard a drive click:

 

However, the ST4000 drive noted after those errors is NOT the cache drive, but one I used with Unassigned Devices as a storage/transfer drive - so could be unrelated too.

 

Is there anything else I should be checking, or just get the RMA'd drive and see how it goes.

 

Cheers!

Diags are after rebooting and you didn't capture the beginning of the problem, SMART for the disk looks OK, but clicking noises suggests it might not be, you can replace/swap cables to rule those out and try again.
