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.) - Toralf
