Paul,
Looks standard except from one thing...
I sure was assuming you had an unbroken setup.
Sort of a shock that you are on 1 disk now
Well I'd rather not go on before we cannot work
on a drive where you can at least make 1 mistake
without getting everything killed but here's the proceedings:
-Basically we safely copy all your stuff from the array drive to a new formatted HD,
(residing on /dev/hdd = secondary slave, momentarily removing what's there now (if anything))
-The partition arrangement basically is identical so:
raiddev /dev/md0 --> device /dev/hdd1 = "/boot" boot drive
raiddev /dev/md1 --> device /dev/hdd2 = swap drive
raiddev /dev/md2 --> device /dev/hdd3 = "/" root drive
-then rearrange fstab on hdd3,
/etc/fstab we make should be as shown here:
--------------------------------------------------------------------------------------
LABEL=/ / ext3 usrquota,grpquota $
LABEL=/boot /boot ext3 defaults 1 2
none /dev/pts devpts gid=5,mode=620 0 0
/dev/cdrom /mnt/cdrom iso9660 noauto,owner,ro 0 0
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
none /proc proc defaults 0 0
none /dev/shm tmpfs defaults 0 0
/dev/hda2 swap swap defaults 0 0
//amd900/backup /mnt/backup smbfs username=paul,password=paul4636
---------------------------------------------------------------------------------------
-then remove hda and plug our "newhdd" there.
Since I see your tape drive in the fstab I feel compelled to mention that you could
even do that with mondoarchive if you use that as backup solution (see the HowTo)...
... but NO we are not going to do it with just one "live" HD
PM me when you get a 2nd HD and I'll be glad to describe in more detail
- meanwhile got a rush job till monday

Regards
Reinhold
