Hello,

 

That's the second time I run parity check and get around 20000+ errors while none of the disks show any errors. What errors are they? Where do I find and correct them?

That was a non correcting check, run a correcting check, it should find but this time correct all the same errors, then you can run a non correcting one to confirm all is well.

The checkbox "Write corrections to Parity" is always checked on the Main page. But these last 2 parity check that ran ran because of "ungraceful shutdowns" so I did not started them myself (and that is weird because in fact I only chose to reboot).
So you think that these self started parity check ran without the "Write corrections to Parity" activated?

Auto parity check after an unclean shutdown is always non correct.

Auto parity check after an unclean shutdown is always non correct.

7 years with Unraid and I never knew that. Thanks

It wasn't always like that, but it has been since about 3 or 4 years ago.

So right after your answer I started a Parity check manually with correction. And a day later I get this exact same result with 20500 errors.
I am concerned because I have 2 X 4Tb parity disks and I don't know what will happen if I lose a disk,  will I be protected?

Even when I run the Extended Fix Common Problems plugin it ends with a Found Errors notification, but no errors appear on screen to be corrected.

Jorge this is unclear to me. In 4 days I had 3 parity checks that ran. 2 unrequested and one actionned manually. All of them finished with around 20500 errors. Those errors are not detailed. Isn't there more information in the syslog about that? Is there a debug mode? I would like to be reassured that I have parity on my server.

Only the last one was a correcting check, so it's expected to find exactly the same errors, next one should find 0 errors.
