dsharp9000 Posted June 20, 2022 Share Posted June 20, 2022 I think this is due to an unclean shut down when we lost power; but im unsure how to proceed form here and what further checks i need to do or if i need to replace a disk. I have very limited knowledge on how to resolve errors in unraid with regard to the array or how to interpret the results...... any help would be appreciated. I have ran a parity check twice... each time it did the same thing...5 errors. The array is still running and the disks appear to be operating normal; but the 5 errors makes me nervous as am thinking something is wrong somewhere.

itimpi Posted June 20, 2022 Share Posted June 20, 2022 Once you have any parity errors reported then you will continue to get them reported until you run a correcting parity check, after which if there are no further issues you will get 0 errors reported. Quote Link to comment
dsharp9000 Posted June 20, 2022 Author Share Posted June 20, 2022 (edited) thanks for your reply. My settings show write corrections to parity and still get the 5 errors... not sure if i unwisely should of not of set this box to write corrections to parity as its default...can i run a non corecting parity check then a correcting parity check .... or perhaps i need to do something else?

itimpi Posted June 20, 2022 Share Posted June 20, 2022 When you run the correcting check then it would report the same 5 errors but would be correcting them. I can see in the diagnostics a correcting check being run and correcting 5 errors. You should now be able to (optionally) run a non-correcting check and get 0 errors. Quote Link to comment
dsharp9000 Posted June 20, 2022 Author Share Posted June 20, 2022 im going to run a non correcting parity check just to be on the safe side..... should i keep this set at non correcting from now on?... Also, if i run a correcting check "after" the non correcting check will the 5 errors still show up in the correcting parity check?... im just curious if the errors will always be there everytime i run a future correcting parity check "if needed"..... its just a bit confusing to me; please forgive my lack of knowledge regarding this. I appreciate the help on this. Quote Link to comment
itimpi Posted June 20, 2022 Share Posted June 20, 2022 The scheduled check should be non-correcting as you do not want a dtive that is playing up potentially corrupting parity. Normally you only run correcting checks when you are reasonably certain you have no outstanding hardware issues. Once you have run a correcting checks then subsequent checks (of either type) should show 0 errors. You then want to keep a watch on the server to see if you ever get any parity check reporting a non-zero value when not expected. Quote Link to comment
