http://ubuntuforums.org – Hello all, I'm new to Ubuntu and server administration in general, but have been having good times with several Ubuntu 12.04 servers I've set up at my company. I had believed I had properly set up a software RAID-1 array during Ubuntu installation on one server, but when I learned more about the mdadm tool, I discovered the RAID is degraded and one of the disks is "removed" Code: sudo mdadm --detail /dev/md1 /dev/md1:         Version : 1.2   Creation Time : Fri Mar 29 23:20:08 2013     Raid Level : raid1     Array Size : 8112064 (Hardware)
