Hi folks, hopefully this will be a quick one to answer.

 

I'm using UNRAID 6.8.3. I've been hesitant to upgrade the OS because I feel the need to replace a parity drive throwing SMART errors (see attached screenshot) with an exact replacement. My question is whether replacing a parity drive differs from the instructions for a standard data drive?

 

There is a "parity swap" procedure guide online, but it seems only relevant when replacing:

"a data drive with a larger one, that is even larger than the Parity drive."

 

Use the standard replacement.  However before you do you may want to post your diagnostics here for the gurus to look at your SMART data as it could be a cabling issue and not the drive.

I went into the self-test section, downloaded and attached the SMART report for this particular drive. It would be amazing if folks with the know-how can read it properly.

 

For context, pre-COVID times, the server got a light knock (foot grazed the chassis in passing by a relative) and a few hours later it this drive was spitting SMART warnings. I opened it up at the time and reseated all SATA/power cables at both ends that same week. Chalked it up to a temporary lapse of connection. Year or so passes, array health checks pass, but I get additional warnings at random sprinkled in between the months (I live remotely from server nowadays, thanks to COVID).

post your diagnostics

Tools - Diagnostics

Run an extended SMART test on that disk.

Hi folks, 

 

I've run the extended SMART test and posted the diagnostic zip results from Tools -Diagnostic.

Extended test passed, you can acknowledge the SMART warning and keep using that disk for now, just keep monitoring.
