[plug] HELP! servers boots in ro mode only

[Andrew Barbara]

yes that is correct, you may be able to run fsck under the linux on the
floppy and fix the problem, not sure.

Thanks for your reply Andrew, this could be a lifesaver. I just wanted
to confirm that what I need to do is to boot using a floppy (or
something like Tom's Tiny Linux) and then edit the line in /etc/fstab

/dev/hda3    /    ext3    defaults, errors=remount-ro

becomes:

/dev/hda3    /    ext3    defaults, errors=remount-rw

Will this make the system reboot in read-write mode? Should I fsck
whilst I've got the system booted from floppy?


Thankyou,
sol
