Super slow parity sync speeds

Recommended Posts

Hi!

I have started to get super slow parity sync speeds (~2MB/s)

 

Have been scratching my head on this one for a while and my syslog does not look like any other i have seen on similar support threads.

I have run a Disk speed benchmark and even though some disks are slower they are nowhere as slow as the parity sync.

I am hoping there is someone here who has a better understanding of whats going on then me :)

 

 

EDIT: After reseating Disk 3, 4 and 5 both Power and SATA cable the speeds are back to normal, thanks for the help!

You are getting continual resets on the ata1 device (from the information you posted we cannot tell which disk this is).   This sort of problem is nearly always related to the cabling to the drive (sata or power) so that needs checking carefully.

What more information/logs would be needed to determine which disk is the problem?
