[ubuntu] mdadm degraded raid5 array?

view full story

http://ubuntuforums.org – After rebooting my server this afternoon I noticed that after booting the OS from grub, that the system complained that my raid5 array was degraded. It offered to boot to a command line, or also offered to start the "degraded" array and ended up booting normally after a quasi-verbose boot. I'm in the OS now, and things _seem_ to be working normally. Here is the output of sudo mdadm --detail /dev/md0 Code: /dev/md0:         Version : 1.2   Creation Time : Sun Apr 29 20:04:55 2012     Raid Level : raid5     Array Size : 29 (Hardware)
