Parity Drive Fail on New Server and New Drives

[Rallysports]

Hey All,

 

Had a weird occurrence last night as I was doing another bulk copy of my data to a new server.  Around 3:55am the parity drive (GU28Z) showed in error state. Then a minute later it showed errors on the rest of the array drives.  These are all brand new 10TB WD drives and all went through the preclear process.

 

After a reboot I show no errors but the parity drive is disabled.

 

Currently I am performing a "Read Test".  I have read in other posts that if nothing is wrong with the parity drive then I can reassign it?

 

I am not sure how to determine if the drive is ok.  I am wondering if I may have had a power issue or something.  The new server is on my desk currently and not yet protected behind a UPS.  Was going to move it down once I had everything running normally.

 

Any help would be appreciated.

 

Thanks

Diags are after a reboot so we can't see what happened, but the description suggests a controller issue, for now resync parity, if it happens again grab diags before rebooting.

Hey johnnie.black,

 

I have to say I panicked and did a fear reboot hoping everything would be ok afterwards.  I will remember this next time to pull the logs before.  I am currently just using onboard SATA. Could this maybe be a Mobo thing?

 

To resync the parity do I just need to wait for the "Read Check" to finish and then there will be an option to resync or is it more in depth?

 

And thanks for the quick response.  One of the reasons I love UNRAID is because of the community support.

Cancel the pointless read check. To rebuild a disk to itself, whether parity or data, stop array, unassign disk to be rebuilt, start, stop again, reassign disk to be rebuilt, start again to begin rebuild.

Yes, I've seen it a few times on the forum before with Ryzen boards, the SATA controller stops responding.

I have debated getting a SAS controller and going that route to allow more drives as my Mobo SATA is maxed out.  I wonder if that could take the strain off as that is what is in my prior server that has been running for 5+ years.
