Repeated Raid1 Failures after upgrade to Lenny
So I upgraded to Lenny over the weekend, and now I'm having issues with my RAID1 were there weren't any before. Every few hours one of the devices making up any /dev/md will fail. It's usually on /dev/sdb but it's happening on /dev/sda as well. I can set the device faulty in mdadm and then readd and it builds fine, but then fails again 4 or 5 hours later. I'm new to Linux software RAID so i'm hoping someone can point me in the right direction.
Here's some of the output from dmesg:
