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.
You formatted gave that partition on /dev/hda a RAID type. So it will be
impossible to access it directly that way. The best thing to do is to
add a disk, copy everything over and then reformat the disk with the
RAID partition and copy it all back. Or else keep everything on the new
disk.
I don't think that's really necessary, since RAID1 is mirroring. I've been
able to mount the individual partitions (with RAID not running) as regular
linux partitions (usually ext3) with no untoward effects. The RAID superblock
doesn't seem to interfere with the file system.
All that's necessary is to change the partition type so that the kernel
doesn't identify it as a RAID partition and keep trying to start the array.
You can then zero the RAID superblock for good measure.
Of course the even better thing would be to rebuild your RAID array with
such a new disk. raidhotadd is your friend. Don't forget to modify your
/etc/raidtab if you go that way.
I would recommend using mdadm. I found it much easier to learn and very
reliable.

Hi guys ,
Thanks a mill for your inputs.I basically removed all the info in the
raidtab file and then rebooted the OS , and it seemed all worked fine
now. I am just concerned that the superblock may become corrupt? (sorry
limited knowledge and paranoia talking here).
