You can use the sed line mode edit command to modify fstab, or link the disk
containing /etc from another Linux instance, and vi it from there. I would
try sed first, after making a backup copy of course.

Subject: LVM Mistake - How to recover
Greetings List-ers,
I seem to have painted myself into a corner. I'm hoping someone on
the list has either seen this before, or knows how to recover.
I'm running SLES9 under z/VM 5.1. I needed to add a couple of MOD3's so I
could set up an LVM volume, so I configured the available DASD in USER
DIRECT, committed the changes with DIRECTXA and brought up the guest. In
YaST, under SLES9, the LVM module could see the DASD that I added, so I
added it to the logical volume. I applied the changes and set a mount point.
When I applied those changes and went to leave, it complained that the DASD
was invalid and that I needed to reboot. After doing so, I am unable to boot
normally (invalid file system bring the system to a screeching halt); I'm
stuck booting to Single-User mode. I need to get into the /etc/fstab file
and edit out the line for the logical volume mount, but I can't seem to
figure out how to edit the file. vi will not work through the console and
since I am in single-user mode, networking is not available.
Any suggestions on how I can edit the file and comment out (or delete) the
erroneous line in /etc/fstab?
Many thanks,
