Hi!
I'v installed ubuntu server 13.10, configured two disks for raid 1 at installation and also configured lvm at installation. System is booting up correctly, mirror is synced, but when i disconnect any of hard drives system won't boot anymore and is stuck on emply black screen. What could be the cause of that.
