I am trying to resize a file based guest DomU while it is shut down. It seems 
that all the information that I can find relates to resizing ext3 file systems 
and there in no information (that works) on Reiserfs.

The first thing that I try to do is to verify that Reiserfs tools work, so I 
execute this (hda is the domU file system file):

reiserfsck --check hda
Don't *EVEN* think about trying these tricks. Seriously. Back up the partition, rebuild it from scratch, than pour the backup onto the newly built and enlarged partition.

Reiserfs has, in my experience, been a source of serious fileystem grief. Given that its core developer has a habit of casually losing really important things, including his wife's corpse (no, I'm not kidding, look for hte keywords "Hans Reiser murdered wife"), I've been unshocked by the repeated file lossage when trying to do even modest system operations with Reiserfs.

Keep it simple for reliably. Back it up and rebuild from scratch.
