Sync errors, how to proceed?


Recommended Posts

On my last two non correcting parity checks I can see 7741 sync errors, is there any way to figure out which drive is causing these errors? In the logs it simply shows the sector numbers. 

 

If I can locate the failing drive and replace it, will non corrupted versions of the data be restored from parity?

Post up your diagnostics in a new post.  Hopefully, one of the Gurus will take the time to look them over.

 

Then, I will make this observation.  99% of all sync errors are caused by something besides 'bad' drive or 'bad' data on a drive.  (Either of these will be throwing up other errors...)  Unclean shutdowns account for about 2/3 of the errors and the balance by other hardware problems.
