Read errors on parity while rebuilding data

Featured Replies

I bought 2 18TB to swap my 2 1TB drives, I first swaped the parity disk and let it rebuild and everything went fine, but today, while rebuidling the data on the other disk, I noticed a huge slowdown followed by some read errors. The data rebuild finished with 184 read errors on the parity drive, but everything seems active and the short SMART test result for both drives says completed without errors. I am now running the extended test to see if further errors arise.

 

I see disk read errors in the logs, examples below. Could these errors be because of a bad SATA connection or something like that? Since the disks are new, is there a possibility that they don't work properly even though they passed the tests? I'm a bit new to unRAID and this is my first time swaping disks so I'm a bit affraid of breaking something.

 

Thanks!

 

 

EDIT: I just saw on this on the identity part of the parity disk, could this be because of a cable connection issue?image.png.466c823d486ae7103fa2664299f56ef9.png
