Liquidbings Posted November 4, 2019 Share Posted November 4, 2019 Howdy folks, Just wanted to say hi and introduce myself to this wonderful community! Been loving UnRaid and everything that goes with it! Yesterday the monthly parity check ran and came up with 15 sync errors. From everything I've read and deciphered so far it seems this can be normal if there have been any dirty shutdowns, and I believe there may have been 1 or 2 during a couple bad storms we had. (on a side note if anyone could recommend a good UPS for my system lol). The thing I could find in the logs that looked related was this bit Quote Nov 3 00:30:01 TowerX2 kernel: md: recovery thread: check P Q ...

Thank you kindly for any and all help you may be able to provide. towerx2-diagnostics-20191104-1137.zip Quote Link to comment
itimpi Posted November 4, 2019 Share Posted November 4, 2019 If you have had an unclean shutdown then it is normal to expect a few parity sync errors as the system would have not been able to complete housekeeping and tidily unmount the drives. Typically such errors occur near the start of the parity sync process. Quote Link to comment
Liquidbings Posted November 4, 2019 Author Share Posted November 4, 2019 Thank you kindly for the quick reply. That seems to correlate to what I see. The Check starts to run at 12:30 and 13/15 of those errors were within 18 seconds of that and the other 2/15 were within 6 hours of a 23 hour run. I will likely run another check and see what comes up the second time to be safe. Quote Link to comment
