/dev/VGNAME/LVNAME -- those are the devices you mount.
Thanks.

I realise this. But the disk I'm trying to mount is built the same way as the new disk I've built. So the both have a VolGroup00. What I would like to do is to either understand how I can change the volume group info so it will become a distinct volume group, and then I can 'import' this into my new environment, or how I can get into the block system so I can access the filesystem structure it embeds.

This is where I'm struggling. I would like to create a VolGroup01 device file, rename the volume group within the physical volume, and then mount that. Is it possible to 'hack' the old drive like this?
