[plug] HELP! servers boots in ro mode only

[Andrew Barbara]

I the /etc/fstab there is a switch to remount the filesystem in read only
mode on filesystem errors, maybe you need to boot into a linux floppy disk
or even the Linux install CD (I know the RH boot CD works) and change the
file this way, or you may be able to run fsck this way.

Subject: [plug] HELP! servers boots in ro mode only


I've got a nasty problem I don't know how to solve. I've got a PC
running as a network server that boots in read-only mode. There are
certainly errors in some of the blocks. (I think this problem was caused
by two power outages in quick succession, the second whilst the machine
was rebooting.) It has an ext3 filesystem and e2fsck doesn't seem to
work. If I could just get it to mount in rw mode I'd be able to fix
everything else I think. I've tried:
mount -t ext3 rw /dev/hda2    #the boot sector
mount -t ext3 rw /dev/hda3     #the root partition
But nothing on the hard drives seems to mount. Have I done something
wrong here? Or am I on the wrong track?

In conjunction with this I was wondering (because "rm" didn't seem to
work and there was no way to log onto gnome, yet "ls" and "less" did
work) what executables work? Is it apps that involve reading only, or is
it apps in /bin or /sbin or something like that?

Any help greatly appreciated.
