[bitfolk] VPS Disk Reset

I'm stuck on the old disk layout which is hiding 0.5GB of disk away from me, and I think I'm going to buy a 5GB upgrade, so I wondered about fixing all this in one go. I don't want to reinstall the OS though, so my plan is request/get the disk upgrade, then to boot into the rescue environment and as root, cd myvpsfilesystem tar -c . | ssh somewhereelse "cat > filesystem.tar" Then do the Xen disk reset, allocate the new space, then boot to rescue again, mkfs with label "root", then: ssh somewhereelse "cat filesystem.tar" | tar -x I've thought about the disk block ID being different after this, but it's not in fstab or anywhere else I can find. As I understand it pyGrub will also just work. The question is, am I heading for any pitfalls? Thanks for any opinions. Chris Tallon
