[Resolved] Array has 1 disk with errors

[FreeMan]

I'm still on 6.8.3 and would prefer to remain there until I get this resolved, if possible. The fewer pieces changing at once, the easier it should be to track down...

 

While my parity check was running yesterday, I got this notification:

 

Unraid array errors: 2021-03-01 22:24
Warning [NAS] - array has errors
Array has 1 disk with read errors

 

Looking at my Array devices display, I see that disk 8 is reporting 256 errors. Of course, the warranty expired on 16 Feb 2021, so I've got that going for me...

 

The parity check finished with no indication of error whatsoever. This disk has never, it appears, had a SMART self-test run, so I ran a short-test which completed without error and that's in the included diagnostics. I've got a long test running and will post results when that finishes.

 

If anyone can tell me if this is starting to look terminal, I'd appreciate it.

It's logged as a disk problem you should run an extended SMART test.

Here are the results of the extended SMART test. unRAID reports "completed without error".

Then and assuming the emulated disk is mounting correctly you can rebuild on top, keep monitoring the disk, especially this one:

 

ID# ATTRIBUTE_NAME          FLAGS    VALUE WORST THRESH FAIL RAW_VALUE
 187 Reported_Uncorrect      -O--CK   098   098   000    -    2

There's no emulation involved - every disk appears to be mounted just fine:

 

 

Would you still recommend a disk rebuild, or just acknowledge the error and keep an eye on the disk? I'll probably make myself a reminder to do an extended parity check on it at least monthly, if not weekly.

Yes sorry, sometimes I get the threads mixed up, just clear the errors and keep monitoring.

No worries! Just making sure. There's probably nothing critical on this disk, so it wouldn't be a crisis if I lost data, but I would rather avoid it, and I'm never afraid to double check.
