Troubleshooting Red X on parity disk

[mostlydave]

My parity disk has been disabled with the following SMART notifications:

 

Attribute = 5Reallocated sectors count

 

Attribute = 187Reported uncorrectable errors

 

Attribute = 188Command time-out

 

Attribute = 197Current pending sector count

 

Attribute = 198Uncorrectable sector count

 

Attribute = 199UDMA CRC error rate

 

188 was unchecked

 

Is this disk shot? What's the best course of action from here?

The red X disabled disk is a separate issue from the smart items, unraid doesn't disable a disk because of smart stats, only when a write fails.

 

So, you have a disk that shows smart errors (you haven't given enough info to tell how bad those errors are) that also refused to write data when asked.

 

In the absence of diagnostics, I'd say the disk needs to be replaced. The diagnostics zip file may contain information that would change my mind, but I doubt it.

How do I get the diagnostic zip?

 

[itimpi]

Via the Diagnostics option on the Tools menu.

Alternatively it can be generated using the ‘diagnostics’ command from the `command Line with the results being put into the ‘logs’ folder on the flash drive.

diagnostic zip is attached, I would appreciate any insight into the drive.

 

I'm thinking it's not salvageable, but maybe I'm wrong.

Parity disk looks fine, there's a constant "Power-on or device reset occurred" that's it's likely related to the problem, replace/swap cables/backplane slot with another disk and see if errors stop (or appear in the other disk), you'll need to re-sync parity.

Thanks, it looks like the cable was loose, I fixed that and it it rebuilt over night with no errors!
