Hi,
FS mount info are in /etc/fstab only (no further template)
You should get either on the console, dmesg, /var/log/messages some clues about the reason of the maintenance mode.
When you are in maintenance mode, is there any FS you should see you are not seeing ?
Are you using IDE or SCSI ?
with SCSI are you having a correct terminator setting ?
did you make any change in the grub.conf file ?
