Hello,

 

I recently changed my parity disk and an array disk at the same time. The re-sync was going well, then about halfway through the operation I received millions of errors. The actual data is still intact it seems. After the re-sync I pulled several files at random from multiple shares and all look good. I also have a backup worst case.

 

From what I can tell the issue is related to an ATA bus. I am getting this repeating error in the log:

Thanks in advance!

Reseat all the sata and power cables.

 

Also, you can directly attach the diagnostics to the posts. 

Looks like the errors were non-impactful. I did change out the SATA cable for the drive throwing the errors. But honestly I think the source of the problem was pulling a data and a parity drive at the same time and letting it rebuild from the second parity. 

 

At this time the array is green and the drive with the errors is syncing as the second parity once more.

 

I will repost if there is an issue.

 

Thanks!
