Disk Fail - Next Actions

[rts.empire]

Hi All, 

 

Still fairly new here. 

I was just editing my media library (cleaning up duplicates) when I received a warning that a newly added disk has failed. I have 2 questions - 

1 - How do I determine what caused the disk failure - from what I can see the SMART results indicate it is "ok"

 

2 - How do I proceed? The process I have determined so far appears to be: 

Stop array

Unassign disabled disk

Start array with disabled disk unassigned

Stop array

Reassign disabled disk

Start array to begin rebuild

 

Is this correct?

Disk problem looks more power/connection related, but the disk SMART shows some issues, so try replacing/swapping cables (power and SAS) and if issues continue I would replace the disk.

 

There are also issues with your pool it's been dropping a device:

 

Aug 12 09:50:35 UNRAID kernel: BTRFS info (device sdb1): bdev /dev/sdb1 errs: wr 4, rd 0, flush 1, corrupt 0, gen 0
Aug 12 09:50:35 UNRAID kernel: BTRFS info (device sdb1): bdev /dev/sdg1 errs: wr 36552100, rd 60558, flush 3120, corrupt 722097, gen 0

 

Run a correcting scrub and also see here for better pool monitoring.

Hi, 

 

Thanks for the reply

I found the issue, one of the data cables wasn't all the way in - the clip didn't latch. Rebuilt and all is well now. 

 

Thanks for the heads up on the pool - I will look into it
