Hello,

 

Scanned a few threads I could find on this and couldn't find much, can anyone advise?

 

I've ran the parity twice now and got the same amount of errors (1687), there have been no unclean shutdowns to my knowledge and the SMART status' appear to all be fine. 

 

Attached are two diagnostics, one from after each of my recent parity checks.

 

Thanks for any advice.

repeated check still 1687 errors - tower-diagnostics-20180327-1641.zip

after 1st 1687 errors - tower-diagnostics-20180326-2040.zip

First check was non correct, so the 2nd one would find the same errors, 2nd one was a check correct, so as long as no more errors on next check you should be OK.

Ok I’ll kick another one off and see what it says. Thanks.

Then would should be fine, still there needs to be a reason for the previous sync errors, most likely an unclean shutdown.

Would that have meant that if a disk had failed while those errors were present there would have been problems recovering from parity?

Yes, there would likely be some corruption on the rebuilt disk.

Your statement implies that you think that parity contains specific information about user files.   In fact parity has no understanding of files or file systems.   All it knows how to do is to recover a particular sector(s) on a target disk by the combination of that sector on parity and all the other data disks.    If any of the data disks returns invalid values for a sector then the corresponding sector on the recovered disk will be corrupt.
