[Hampshire] Moving partitions...

Hi All.

I'm trying to clean up the disk on my main workstation, and I've hit a
wall...

I want to move a partition. It's now sat just above a big lump of free
space, and I want to move it down so that I can keep shuffling.
Eventually, when the right partition has free space alongside it, I want
to expant that partition & start playing with filesystems.

So far so good - just use parted, thought I. Not so.

parted doesn't want to play with my LVM partitions - I get an error along
the lines of "unknown file system" (can't remember the exact error - I was
booting from Knnoppix at the time). Now I don't actually want parted to do
anything to the filesystem structures (pvresize will do that) - I just
want it to move the data on the disk...

Any ideas?

Thanks!

Vic.
