Disks in error state - is my controller dying?

[Fredrick]

Hi guys,

 

Slightly panicked here now 🥲

 

I've installed a Coral TPU in the M.2 slot, and discovered that using the second m.2 slot disables a couple of my SATA-ports. No worries, I had more slots on my SAS-controller so I moved the SATA disks over there. 

 

Now I must have been careless with a couple of cables because after booting I still could't find the disks. I re-seated cables and tried again. Array went up fine, but after a short while Disk 3 and Disk 9 errored out and was emulated. I rebooted, did short SMART tests and then started a re-build. Disk 3 finished first (on account of being just 4TB), but again errored out while Disk 9 was being rebuilt. 

 

Seeing as Disk 3 was my oldest and smallest disk I decided to buy a new and just replace it. 

 

However when I'm currently preclearing this new drive I see Disk 10 error out which has me very concerned. I'm in the midst of a big preclear / rebuild and I'm without parity protection. 

 

I'm attaching diagnostics that I fetched yesterday (when the old Disk 3 was still present) and current diagnostics which is during the rebuild. Any advice on my course of action to maximize likelyhood of success would be greatly appreciated. Thanks!

Look more like a power/connection issue, Samsung SSD also dropped, check/replace cables.

Ah yea I'd forgot about that. I've actually got a new (well used but newer) PSU lying around, maybe this is the right time to get it swapped in (after preclear and rebuild of disk 3 I guess). 

 

Any other tips other than just having it preclear and rebuild without touching the server at all risking a new jank to appear?

Not really, just do that and try again.
