Move data LVM from fedora install to new gentoo install?

I have a box with Fedora 9 on it on sda. This drive is the entire fedora install, and just a normal drive, nothing fancy.

There are 3 other drives in this box that are part of a large LVM mounted at /mnt/share under Fedora.

Since Fedora 9 is no longer supported and I like Gentoo better, I want to install Gentoo, and continue to use the LVM without losing or needing to back up 900gb of data from it.

Can I do this?

Is it as easy as just finding out the LVM info from Fedora and telling Gentoo? Is there another step to this?

Thanks in advance.

Take a look at this doc, it goes step by step on how to do this.

Thank you.

I followed that and ran into a little bit of trouble.

I have three drives. I'll call them a, b, and c for simplicity.

I didn't realize drive c was not actually online (it could be failing? its a maxtor). When I did vgimport VolGroup00, it wouldn't let me because it couldn't find one of the UUIDs. It told me to remove it, so I did. Then it said 2 drives in the volume group. I rebooted at this point and drive c came online, but was no longer part of the lvm. I ran vgimport without C, and then added C back into it.

When I run vgchange -ay,
