LinuxQuestions.org - LVM: Deleted my system VG0 and reinstalled system, can't find VG1

I used to be a linux geek... then I went to albania for 2 years. I had all this cool stuff set up on my computer and now I have no idea how to use it.

I had been experimenting with LVM2 so I created 13 partitions and used a few small ones as normal /, /boot, swap, etc and the rest I used as LVMs. The partitions were in two groups vg0 and vg1. The one group contained lv named things like vg0-var, vg0-opt, vg0-home, etc that corresponded to /var, /opt, /home, etc. The second was my storage space.

When I came home my system was all messed up from family use and not remembering anything about linux I simply reformatted the partitions that were solely attached to vg0 as reiserfs and reinstalled the latest version of Ubuntu (7.10)

I've installed lvm2 but now I don't know what to do to safely re-add the lvm partitions to vg1 and get back my stuff.

here's what cfdisk thinks of my hard drive:

When I run vgchange -a y I get

Code:

  Couldn't find device with uuid 't2iDpK-GAXD-5QzZ-XJz4-jWWR-W4mk-2ZjRGe'.

  Couldn't find all physical volumes for volume group vg1.

  Volume group "vg1" not found

I think that I may have deleted one of the partitions by accident but then put it back right away without changing any data on it.

Is there any hope of running a few simple commands to get this stuff back? If it would take me more than 2 hours it's not worth it. The only stuff not backup up on my DVDs is a few TV shows and a ton of music I got from a friend.

I'm more interested in learning how to do it for the sake of knowing and being able to help someone else in the future than out of desperate need.
