ATA softreset failed (device not ready), now slow RAID
 

Hi,

Recently did an apt update and upgrade to my CLI only Lenny server. Upon reboot I get an "ATA softreset failed (device not ready)" for all of my SATA drives. I noticed the upgrade changed the kernel to "Linux debian 2.6.26-2-amd64" (do have 64bit CPU).

Once loaded to a command prompt I can assemble my raid 6 array with the command "mdadm --assemble /dev/sda to sdd" then mount it with mount -a. But transfers to the array are horribly slow ~1mbs.

Upon reboot i get the same errors and have to assemble my array every time.

Does anyone know how I can amend this situation?


Thanks for your time

I'm guessing your array is slow because it is rebuilding. If you check mdadm -D /dev/arrayname, you can wait until it's rebuilt and clean, then check the speed again.

On the other hand, it could be something else. I found this https://bugs.launchpad.net/ubuntu/+s...id/+bug/449876
which sounds a bit similar if you've used "fakeraid" and dmraid in the past. Basically, you need to use -nodmraid as a kernel option.

On the other point, when you update, I believe you have to update your initrd manually. Did you run something like?
