nekromantik Posted October 1, 2020 Share Posted October 1, 2020 hi all I set up a parity drive last month and set up a parity check once a month. however I was not aware you should not use correcting checks on these ones. One just finished last night and it found 8 errors. Should I be worried? Attached are diagnotics. Thanks tower-diagnostics-20201001-2220.zip Quote Link to comment
JorgeB Posted October 2, 2020 Share Posted October 2, 2020 Any unexplained sync errors a reason to worry about, any unclean shutdown before this last check? Quote Link to comment

Nope no unclean shut down. So the correcting scheduled checks are ok? Or leave it non correcting? Quote Link to comment

Then you should try to find out what caused the sync errors, only acceptable result is 0 sync errors, run a non correcting check, and scheduled checks should also be non correcting.

How will I know what caused the errors? Will syslog contain errors? Can I write to array while check is running? Quote Link to comment

If there was no unclean shutdown it's a hardware problem, RAM, board, controller, disk, etc. 5 minutes ago, nekromantik said: Will syslog contain errors? It only shows the sync errors, not the reason for them, though it can help diagnosing, by comparing with previous errors. 6 minutes ago, nekromantik said: Can I write to array while check is running? Yes, but array will perform slower. Quote Link to comment
nekromantik Posted October 2, 2020 Author Share Posted October 2, 2020 hmm ok some time I see people posting 1 or 2 are normal. Its a brand new sata card and hard drives and I ran pre clear on it without issue. Quote Link to comment

trurl Posted October 2, 2020 Share Posted October 2, 2020 A few are normal after unclean shutdown, but they still must be corrected. Zero is the only acceptable result. If your array isn't in sync you can accurately rebuild a disk. Quote Link to comment
nekromantik Posted October 2, 2020 Author Share Posted October 2, 2020 if the new scan I see more errors what would you recommend? if its the SATA card issue how would I confirm? Quote Link to comment

Post new diagnostics. If we can compare them in syslog, that would tell what the suspects are. RAM is also a suspect if different parity checks result in different parity errors for example.

nekromantik Posted October 3, 2020 Author Share Posted October 3, 2020 (edited) so parity check finished with 0 errors. so looks like Im good for now. attached is diagnostics after the last run. tower-diagnostics-20201003-1117.zip Edited October 3, 2020 by nekromantik Quote Link to comment
JorgeB Posted October 3, 2020 Share Posted October 3, 2020 Run always non correcting checks from now on (unless there's an unclean shutdown), if one finds more errors in the future immediately run another non correcting check without rebooting and post those diags. Quote Link to comment
nekromantik Posted October 3, 2020 Author Share Posted October 3, 2020 ok thanks Quote Link to comment
