Hello panthrap,

I don't use LVM kinda for what you are going through here. Also because it's advantages don't seem to offer much for my simple systems on home computers. But many people here do use LVM, and they see plenty of advantages even for small systems. Here is a short uncluttered thread with a simple HOWTO...

Howto mount a logical volume (LVM)

I think you've done all but the final step.

I may start playing around with LVM just for the aggravation.

Why wouldn't the filesystem type for LVM be just ext4 when a filesystem needs to be mounted over several physical volumes in an lvm ?

I am gonna have to experiment with an F18 logical volume group that I now have
and I will want to pull files off of after mounting on a Fedora 15 KDE plasma workspace.
