Your way has more guarantee you won't lose data, and they can have a backup disk on their system, which is nice! I understand why you make this suggestion. I stick in backup disks on systems I setup now...
back to what I was saying: make raid volume, set partition bits,etc. like such, add in new disk, set up a degraded raid 1 volume with two members on disk2,volume only has 1 member currently. Then mount raid volume on disk2 Then copy everything from hda1 to hdb1. oh yeah install kernel with raid support compiled in,and network card support compiled in, as it might have problems with modules... Then make new lilo entry and set root to /dev/md0 reboot, and it come up in the raid volume. Then stop the first parttion, wipe it and then hotadd it the /dev/md0 extending the raid volume to encompass both disk. Wait for it to sync, then rewrite lilo. Then reboot, and it should come up. Even if you completelly clear a partition but don't format it you can still boot from hda1 to a raid volume. I did this accidentally and the system still booted even though hda1 had no partitions on it. mkinitrd also complains about not having raidtools2, and I could never figure it out. Yes I installed raidtools2. --Luke -- --Luke CS Sysadmin, Montana State University-Bozeman -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
