Debian and RAID

When you moved the drive to a different controller it's name would have
changed. I would probably need a little more information but basically
if the drive was

/dev/hda

and you moved it to another controller it could be something like

/dev/hdg

If you can still boot to a root partition or with the Debian rescue disk
try this...

1 boot to Debian rescue install but don't start the installation

2 hit <alt><f2> and activate the terminal there

3 #cat /proc/partitions

4 see if you can see the partition that your new raid device is on
(check sizes etc)

5 reboot to boot cd but instead of going into the install type

6 rescue root=/dev/hd(whatever you found in /proc/partitions)

if you don't find the drive in /proc/partitions than you will need to
load the driver for the ide raid card. Ask again later if you don't
know how to do that and you have this problem.
