Hi ,
I know this is a bit off bacula topic probably. I want to remove RAID1
from a disk , everytime I boot it it's looking for the 2nd disk. I want
to simpy boot into a normal "vanilla" disk. Can I edit the fstab and
just change the /dev/md0 device to whatever the disk is (/dev/hda) ? I'm
really at odds here , if anyone can maybe help me or point me in the
right direction that would be great.
Thanks in advance!

Danie,
Tread cautiously here, as you easily can loose everything!
FIrst, run mdadm --detail /dev/md0 to find out exactly what partitions are
included in the md0 device. The last two lines or so should give you the
information.
Run mdadm -S /dev/md0 to shut down mirroring.
Use cfdisk /dev/hda. Change the partition type for the relevant partition(s)
from FD (RAID autodetect) to 83 (Linux). Write & reboot. When you reboot, no
RAID components should be detected and you can mount your partition(s)
normally. (Edit /etc/fstab appropriately before rebooting.)
BACKUP, BACKUP, BACKUP!!! (Wouldn't hurt to backup your partition table with
sfdisk -d, as well.)
A similar way to do this would be to boot from a Knoppix disk. Make all the
changes & then reboot.
That sounds like an interesting experiment I'll try once on a machine
where the data doesn't matter. I hadn't thought it would be able to work.
