how to modify size of swap with a lvm partition?

Question

I'm trying to add/modify a swap partition on my LVM-formatted hard disk by using GParted from a LiveCD. I only see one big partition taking up the whole disk.

Is there a hidden swap?

Does an LVM-formatted system even need a swap?

I'm using Ubuntu 12.10.

Answer 1

Whether you use LVM or not has nothing to do with whether you need swap or not.

To view LVM logical volumes, run lvs on the command line, or use the GNOME Disks utility.

The version of GParted that ships with Ubuntu 12.10 does not support LVM. It only sees physical volumes, and cannot resize or move them.

However, the latest version of GParted does support LVM. I would download the GParted Live CD and use that.
