Moving a disk and it's data from one LVM to another

[feenster99]

Hi all,
I am trying to simplify my storage on a Ubuntu 7.04 server that I run. It currently has 2 x 500GB SATA drives in a RAID-1, setup as an LVM (called "user_data"). I've also got 2 x 300GB SATA drives in a RAID-1, which I have split in half, and started to build up a new LVM from (called "users"). Therefore, there is now a 600GB LVM, with 300GB free space.

What I want to do, is move one of the 500GB disks into the new LVM, but without trashing the data, and having to re-copy it. Is this possible? I know it would be easier to use fresh disks and re-copy the data, but that isn't possible in the situation.

Cheers,
Matt

Sounds like a plan. Not sure why I didn't think of compressing it all :S Silly me. I guess I just assumed there would be some command that would move the complete LVM and merge it in with the new one.
