I have a degraded RAID1 device (1 disk) from OpenMediaVault.
I've no problems mounting the disk in OpenMediaVault (Debian). But I can't in Ubuntu. After I install mdadm the RAID device doesn't show up when I do cat /proc/mdstat.
If I reboot the system, Ubuntu won't boot, it just hangs with black screen.
Any help please? Should I install any other packages? The installation of mdadm was without any problems.
I'm running Ubuntu 12.10 64-bit on a Pentium 4.
