January 22, 20215 yr Community Expert Were those scheduled parity checks? Whether scheduled checks correct parity depends on the setting in Scheduler. Usually you will want scheduled checks to not correct in case you recognize you had some problem that would have made it wrong. How long have you been running with parity out of sync? Run a correcting parity check and when it finishes correcting parity, then run a noncorrecting parity check to verify you have no sync errors. Exactly zero is the only acceptable result and until you get zero you aren't finished fixing your problem.

Both came back with the same number. All monthly checks have been 0 prior.
January 22, 20215 yr Community Expert On mobile now so haven't looked at Diagnostics. On Main are there any I/O errors in the Errors column for any disk?

I am running out of space, could a space issue cause something like this? I had 2 drives down to KBs left while something was trying to move to them. I am trying to replace a drive to add some more TB's but didn't want to do anything with my parity with errors in it.

I did pull my disk 4 some time around the 13th. Maybe its seated bad? I plan to replace it because its causing a bug in unraid, so rather than wait for a fix I figured I would swap it with another 8TB, rebuild parity, then take that 8tb drive a clear it (hopefully fix the bug) and replace a 4TB drive with that. I didn't start this because I had some work done to my home that required power outages, now that thats over of course I have parity showing issues so now I don't want to do it yet haha.
January 22, 20215 yr Community Expert The check on 1/13 was a scheduled noncorrecting parity check that found sync errors (this was before reboot so can't see it in syslog). Then a manual correcting parity check on 1/21 found and corrected those same sync errors (this according to syslog in those diagnostics). So, run a noncorrecting check to verify that you now have no sync errors.

My scheduler is set to run on the first day of the month but write corrections is on. So this must have been a crash, do those not write corrections by default?
January 22, 20215 yr Community Expert Last check was correct, log doesn't cover the previous one, but next one should return zero errors.
