Converting from RAID1 to a single disk, after failure
I recently had an issue where one of my RAID1 configured drives died on a Debian box.
By die, I mean after post, I am presented with a black screen and flashing cursor, nothing more.
I booted into a knoppix shell and did:
mdadm --assemble /dev/md0 --run -u <UUID of the only working drive> /dev/sda1
I could then 'mount /dev/sda1 /mnt/' and see all the contents as I should be able to.
However, I cannot boot from this device by itself for some reason.
I have reinstalled grub 'grub-install --recheck --rootdirectory=/mnt /dev/sda1' #something like that, can't remember the exact --rootdirectory command without the --help switch, my apologies.
I restarted, with the failed drive unplugged, and again, I'm faced with the black screen, flashing cursor.
Can someone please assist me.
oh, if I've left anything out, my apologies.
