Speaking of which, I think I've found the solution to the snapshot 
issues. It appears that Sistina distribute a patch in the LVM sources to 
fix this problem, but Red Hat (at least in version 8) don't include the 
patch in their kernels. As a result, their kernels support LVM but have 
problems taking snapshots of volumes containing journalling filesystems.

You can get the patch from the LVM sources at sistina.com 
(ftp://ftp.sistina.com/pub/LVM/1.0/ ). It's called 
LVM/1.0.8/PATCHES/linux-$VERSION-VFS-lock.patch in the LVM tarball. I'll 
be trying it on the server at work once I've tested it on my home 
machine, but I thought I'd let you folks know now in case it's of use.

Off we go...
