I have a parity check that is frozen after 19 hrs, at the read check portion. It has been sitting for 4 (or so) hours doing nothing.

What can I do?

I am on unraid 6.12.6

thanks

If parity check changes to read check it means it can no longer check parity.

Your parity drive has disconnected and is disabled. Read check is just checking to see if the other disks can be read.

How long do I let it sit with no change in the read/write data?

Oh, and I just saw that I can no longer connect to the server using my file explorer. It says connection refused. Yet I can use the browser to see what is happening.

I also looked at the "preferences.xls" file and it is empty.

I know this is getting overwhelming, but I just added Aura (Identity protection) and I wonder if that is blocking connections?

Shut down, check connections, reboot and post new diagnostics so we can see if parity drive is connected.

Here it is and the parity drive is not connected.

I would like to be able to run SMART tests on it. Is there a way to do that?

Can you see the parity drive in BIOS?

unfortunately the server is a headless beast and I don't have easy access to the BIOS.

Do you have another disk you can use to replace parity?

No, that's why I would like to run a complete SMART test before tossing it.

I have a copy of the flash drive that is a month or so old. Would it do any good to switch that out and see what happens.

It's from a while before everything went weird. I just wonder if the flash got corrupted...

Unlikely flash has anything to do with whether or not the drive can be seen in the Diagnostics.

Do you mean you disconnected it? Or do you mean you checked connections and the drive still doesn't show up?

If Unraid could see the drive its SMART report would be in the Diagnostics. If you could attach a keyboard and monitor you could see whether or not it shows up in BIOS. If you have another computer where you could plug it in you could try to get its SMART report there.

I'll try that, thanks.

Oh, and I didn't disconnect the drive. When I powered it back up it was showing as an historical drive.

But not as an Unassigned Device?

I just restarted it again and it came up as Unassigned Device.

Attach Diagnostics ZIP to your NEXT post in this thread.

SMART for Parity disk looks OK.

Looks like you started parity rebuild.

Unfortunately, it is having problems with disk6 now. SMART for disk6 also looks OK.

Check all connections, all disks, both ends, SATA and power, including splitters.

Try again.

Make sure all cables have enough slack so they don't pull on the connection. Don't bundle data cables. Ideally, no more than 4 drives per PSU cable. MOLEX-SATA power splitters are better than SATA-SATA power splitters.

When rebuilding a disk, whether parity or data, you should see lots of writes to the rebuilding disk, lots of reads from all other disks, and zeros in the ERRORS column for all disks.
