slow parity sync

Recommended Posts

Hi all


after some help please with a slow parity check. so my array was all fine and then i got some errors on disk 11, unraid disabled the disk. i did a new config to re-enable the disk and also did a smart check which passed.


i kicked off the parity rebuild and am seeing speeds of at max 5MBps but usually hovering around the mid 100kbps range and im seeing at times only 1 drive being read from.


server is a 16 bay rack style with sas backplane, i tested the connections and seem fine. also if anyone has a link to a guide on where to look for stuff in the unraid diagnostic files id be up for brushing up.

It didn't


SMART Self-test log

Disk11 needs to be replaced but since you did a new config you won't be able to do a standard Unraid disk replacement.
