The last week or so I've started getting orange FAIL notifications:

 

Unraid Status	Notice [SINGTHESIS-NAS] - array health report [FAIL]	Array has 9 disks (including parity & pools)	warning	
Parity - ST4000VN008-2DR166_ZGY94KWQ (sdd) - standby [OK]
Disk 1 - WDC_WD40EMAZ-11ZRJB0_WD-WX21D690LHA4 (sde) - standby (disk has read errors) [NOK]

Parity is valid
Last checked on Friday, 01-11-2024, 11:10 (yesterday), finding 0 errors.
Duration: 9 hours, 10 minutes, 24 seconds. Average speed: 121.1 MB/s

 

 But then when I check again Disk 1 SMART says it's managed to exclude the bad blocks (or something like that) and the status is green and 'healthy'. This seems to have happened repeatedly, but I don't know if it's telling me about the same problem multiple times or if the problem is recurring?

 

Is this just something to keep an eye on or should I swap out Disk 1 for a new one ASAP ?

I also installed Scrutiny and that tells me that all the disks are 'passed' and this particular disk is 'passed' for all attributes.

I bought a new replacement drive so I'm ready to swap it out when needed, I just don't know how to interpret this info. There's nothing on the array that's super critical, for e.g. my security cameras use an unassigned SSD to store info to as do my family's PC back ups.

 

Please post the diagnostics.

Thanks for replying JorgeB

Here's the diagnostics - let me know if you need them un-anonymised?

It's not logged as a disk problem, check/replace cables and run another parity check.

parity running now - will be done in about six hours when I'll post back. Thanks

As the report below shows I got another error saying the array was a "FAIL" about 90 minutes before the parity check completed with 0 errors.

Parity-Check in progress.
Total size: 4 TB
Elapsed time: 7 hours, 49 minutes
Current position: 3.63 TB (90.7 %)
Estimated speed: 69.0 MB/sec
Estimated finish: 1 hour, 30 minutes
Sync errors corrected: 0

This is from the dashboard:

 

 

I've acknowledged the warning and the bell icon has gone back to black - so what to do now? Wait and keep an eye on it?

Post new diags, but the warning could be from the previous errors, unless you have reset them.

no more errors since the parity check completed so I'll just keep an eye on it. I have a back up drive ready to go when needed at least.

 

btw how do I reset the errors?

IIRC restarting the array does it, if not reboot.

I rebooted and got a green notification stating 'array turned good'

 

Hopefully that's the end of it, but I'll give it 24 hours before making this as solved.

Many thanks
