October 27, 20187 yr I'm getting lots of parity errors when unraid runs a scan. I have two 6tb parity drives. unRAID Parity check: 27-10-2018 13:24 Notice [MAXIMUS] - Parity check finished (4074 errors) Duration: 16 hours, 56 minutes, 45 seconds. Average speed: 98.4 MB/s This is my latest check. - Any ideas?
October 27, 20187 yr Assuming it was a correcting check run another correcting one without rebooting and when done please post your diagnostics: Tools -> Diagnostics
October 27, 20187 yr Author I get errors on every parity check. I've set it up that every parity check writes corrections. Which files should I upload for diagnostics?

November 2, 20187 yr Author I completed another parity check yesterday, and these are my diagnostics. Around 8400 errors now. maximus-diagnostics-20181102-1122.zip
November 2, 20187 yr Author Thanks Johnnie. Just running another now. it generally takes about 18 / 20 hours to run.
November 3, 20187 yr Author 18 hours 42 minutes, no parity errors. Average speed 89.1 MB/s I assume thats ok?
November 3, 20187 yr Yes, as long as the errors remain at zero for the next ones, it's normal to have some sync errors following for example an unclean shutdown, but if there are more errors without a reason you'll need to investigate.
November 3, 20187 yr Author I've had a few unclean shutdown over the last couple of weeks to be fair, had some power issues at home. I'll run another check today, I think my checks are scheduled at one a week - is that too frequently?
November 3, 20187 yr One a month is usually considered enough, but you should also run one after any unclean shutdown.
