For some reason my parity drive has disabled itself.

• Oct 17 - Parity check finished with 0 errors
• Oct 18 12:20am - Parity is OK according to array health report
• Oct 18 1:02am - Parity disk in error state (disk dsbl)
• Oct 19 - run extended SMART test on disk and it passes
• I am not sure what has happened.  I have rebooted the system, with no change.

I ran an extended SMART test and it passed.

 

Attached is the SMART disk report and diagnostics file.

 

Anyone have any ideas on how to fix?  Is the parity drive toast?  If so why is the SMART test ok?

Diags are after rebooting so we can't see what happened, but seince parity passed the SMART test just re-sync it, good idea to replace/swap cables/slot before doing it to rule those out in case it happens again.

Thanks Jorge.  How do I re-sync the parity drive?  I haven't touched the server in a while - do SATA cables just go bad or become unseated on their own?

They can certainly become unseated slightly due to vibration.

Thanks, I have spun up my parity drive, but it still has a red X beside it and is still disabled.  How do I re-enable the parity drive?

The process is covered here in the online documentation accessible via the ‘Manual’ link at the bottom of the GUI.

Thanks, I will give that a try.

Just to close the loop on this - I finally got around to re-enable my parity drive.  Just as it says in the doc linked to above, I stopped the array, removed the drive.  Restarted the array.  The stopped the array again and reset that drive as the parity.  Then it took about 12 hours to rebuild but now it is good.
