[nzlug] Big Problem... ReiserFS

[Peter Harrison]

This morning I booted up and the machine stopped responding - no mouse,
no keyboard input. I had to do a hard reboot to restart. Only problem
was that X didn't come up. This is a Suse 10.1 machine running ReiserFS.

The problem reported was that X couldn't open /var/log/Xorg.0.log. So I
drop to root and go have a look. If I do a 'ls' in /var/log I can't see
the file - but if I 'vi Xorg.0.log' and try and save is says permission
denied.

If I do a 'ls -a:more' the file shows up. A 'stat Xorg.0.log' says
permission denied. So it Looks like some kind of file system
corruption. 

Problem is I need to run reiserfsck, but I can't do that on a read/write
file system. I've been trying to work out how to remount as read only
but I just get device busy. I installed Suse 10.1 off the net install,
so I don't have a boot CD.

Does anyone know how I might fix this?
