5 errors during parity check... not sure how to resolve..need help

[dsharp9000]

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.

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.

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?

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.

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.

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.
