Super-slow parity check - <350kbs

You are getting a small number of retries on ata1 and ata4 in the syslog but I would not have thought they were enough to have much impact on the speed.


Others have found that this frequently means that you have other disk activity going on at the same time to array drives which is badly impacting the speed.   If you provided your system diagnostics we could determine if this is the case.

When I checked today, disk 13 was red balled - shut it down, swapped in new cable, powered up and unassigned the disk, started in maintenance mode, stopped array again and reassigned the disk to the same slot. Data is rebuilding on disk 13 at 155mbs - so looks like that cable was (very) bad - thank you for the help!
