My last parity check reported 4 errors after an improper shutdown. I recently noticed that I have a bad ups: even slightly moving the power cable between my unraid server and the UPS causes a power loss.

 

So I've had a few improper shutdowns before noticing the issue, any advice on what I should do next ?

 

I've included diagnostics, anything I should add ?

A few sync errors are normal, even expected, after an unclean shutdown, just run a correcting check.

Like this ?

Yes.

Thanks !

I’ll report when the check is done.

 

totally unrelated but are those reading speeds normal ?

Looks right for the disks you have, it will slowdown as it goes to the slower inner tracks.

The correcting check is done. During the check in the main menu it showed 4 corrected errors.

 

However the notification I received when the check was done is this: 

PatricksNAS: Notice [PATRICKSNAS] - Parity check finished (4 errors)

1611707941

Duration: 1 day, 14 hours, 58 minutes, 41 seconds. Average speed: 114.0 MB/s

 

So I don’t know what to make of those results ?

 

 

It means it corrected 4 parity errors. You should run a noncorrecting check to verify that you have zero parity errors now.

Problem fixed, thanks again !
