The root filesystem on my 7.1.3 server (installed from the 7.1 iso) is ext3.
ibays are in /home/e-smith/files/ibays
Data recovery may be tricky as the disks are originally configured using raid - even with only one disk, I think...
When I run 'fsck -AN' I get:
[/sbin/fsck.ext3 (1) -- /] fsck.ext3 /dev/main/root
[/sbin/fsck.ext3 (1) -- /boot] fsck.ext3 /dev/md1
(I don't know if this is useful...)
