Since a lot of people seem to say none of the above can be done, I'm starting to feel slightly unsure, but I though gparted could extend, shrink and move partitions while preserving data.
You would be asking gparted to: 1. Reach inside an LVM PV and shrink one filesystem and its LV, 2. Rearrange the extents inside the PV to make free space at the beginning, 3. Move the start of the PV and adjust all of the starting offsets for the LVs, 4. Finally, enlarge partition 1 into the freed-up space.
Even if gparted was willing to attempt that, there is no way I would trust it to do it correctly.
Quite. I'd never try this without a backup, of course. In fact, I've only ever used gparted in situations where I had a system dump already. Still, it could save you from a bit of work, as in, if it does succeed, you won't have to do a full recovery. Also, I'm not really sure about the state of the LVM support, now that you mention it. (But there is supposed to be *something* in that area.)
Supposedly the below tool should be able to handle LVM volumes, and is bootable from CD. It costs though.
