I woke up this morning to my pc not booting saying that my raid was in
a degraded state. I looked at the raid wiki and it told me to stop
what I was doing and mail the linux-raid list before doing anything
hasty.
Here's all the info that I could find out about it. Any help would be
appreciated.
I am running Ubuntu 12.04
mdadm - v3.2.5 - 18th May 2012
The drive in question is /dev/sdb1 on my system. I tried to look at
it via fdisk but it hangs up. What should my first steps to figure
out if this drive is bad and if so replace it. Thanks.
