May 21, 20206 yr So got the "Parity disk in error state" notification today. At first, I don't see much in SMART (attach diagnostic). I replugged the parity disk's SATA connection and spun back up the disk. I still see a red x next to the parity disk. I have started another parity check but I don't know if the red x means anything right now. What do I do next? tower-smart-20200520-1845.zip
May 21, 20206 yr A red ‘x’ next to a drive means that Unraid is no longer reading or writing to the drive and Unraid has stopped using it. Running a parity check in such a case does not touch the disabled drive - it merely checks that all the other drives can be read without error. The procedure for clearing the disabled state is covered here in the online documentation.
May 21, 20206 yr Author My party check came up fine. I have no idea if this is a real issue or not. Thanks for the link, but I don't know if replacing disks is the first step i should follow here? How can I just get unraid to try the existing disk again? I can perhaps try a new Sata cable but I would like to know how to clear the disabled bit without replacing the disk.

Go to Tools - Diagnostics and attach the complete Diagnostics ZIP file to your NEXT post. 6 minutes ago, Howboys said: My party check came up fine. I have no idea if this is a real issue or not.

Since you have a disabled disk, it didn't really do a parity check, it just did a read check. The posted link also tells you how to rebuild to the same disk, and the SMART you posted looks OK. You should rebuild parity since it is invalid now anyway.
May 21, 20206 yr Author Thanks. Send like rebuild is a pretty involved process - will try it out today. Full diagnostics attached (apologies, first time reporting issues). tower-diagnostics-20200521-0705.zip
May 21, 20206 yr Author Here' what I've done: 1. Stopped the array and unassigned the parity drive. 2. Start the array, then stop and shutdown. 3. Checked disk connections again 4. Power on, add the same disk back as parity (no preclear - I forgot) Now it's doing a parity sync. Hopefully this works. If not, what else can I try? Repeat above with new SATA cable? New HDD?

May 22, 20206 yr Author Seems to have worked? Subject: Notice [TOWER] - Parity sync / Data rebuild finished (0 errors) Description: Duration: 12 hours, 8 minutes. Average speed: 91.6 MB/s Hopefully it doesn't regress in the next few days.
