Had a situation where I inadvertently left an entry in /etc/fstab after removing the storage
on a XenServer 5.6 install. Needed to mount a local Filing System which is abnormal, but a
requirement of an application needing to run in the hypervisor. We could not get knoppix to
run, so had to dig a little bit to find a way to fix the fstab file.
The / partition was mounted as Read Only in this mode.
used:
mount -n -o remount,rw /
and was then able to modify the file that caused me to go into the problem to begin with.
Not really, the main problem was forgetting to take it out before rebooting the first time
