May 17, 20224 yr Hello to everyone! I have an Unraid 6.9.2 with 13 disks and two parity disks . The problem is that I had 1 failed disk from the 13, and now that I am trying to rebuilt a new disk in place, My first parity has errors that are increasing fast and the speed of the rebuilt is dropped to 400KB/sec.... It says that it needs 180 days to finish rebuilding the new 6TB disk... What can I do? Could I disable the first parity and still able to recover my failed disk? Thank you for your time!!!
May 18, 20224 yr Author Oh Yes ofc! I Posted those now... The news are that now my 1st parity is disabled so the disk rebuilt is now fast around 110MB/sec... I am not quite sure that the data will be ok though... Thank you very much for your time, I appreciate it. cupnas-diagnostics-20220518-0956.zip
May 18, 20224 yr Community Expert Solution Parity disk appears to be really failing so you'll also need to replace that one, but the rebuilt disk should be 100% OK as long as no more errors on a different disk, when Unraid fails to read a sector form parity1 it will use parity2, it just took longer with all the errors, but parity2 saved your butt in this case.
May 23, 20224 yr Author Thank you very much for your answer... I just wanted to write that I had checksums from the files, so I checked all the files again, when the rebuilt finished, and all files where fine!!! This second parity truly saved my butt!
