Parity Sync Errors

[opusdeath]

Hi,

 

Recently physically moved my tower and have been getting parity sync errors since. I fixed them but just over 6,000 have returned.

 

I've noticed some SATA connection errors which could be contributing but also I can hear an occasional strange sound from one of the drives so wondered if one might be about to fail?

 

Should I go ahead and fix the errors? Is there anything else I should do first?

 

Thanks in advance.

looks like interface errors, start by changing the cables. once you get rid of the interface error noise, can look at specific drive issues via smart

Thanks for having a look. I've switched the cables and ran a correcting parity check. It seemed to be fixing errors as it went but has finished saying its found 93682 errors.

 

I'm not sure what it is I should be looking at to diagnose?

 

Is the best thing to run another correcting parity check?

When you ran the previous correcting check then all sectors 'fixed' are added to the error count even though they should perhaps not be considered as errors so in that sense the count at the end is normally the number of sectors 'fixed'.

 

You should now run a non-correcting check to confirm that all errors have been corrected.   You could run another correcting check, but if so this to time expect the count to be 0 unless new sectors needing correcting were found.

Thanks @itimpi. I've started the check and will report back. Really appreciate yours and @apandey's help.

Check completed with zero errors. Thanks so much both.
