Pain-free disk space management with LVM

If you’ve never used LVM before, and have been troubled in the past when faced with the heart crunching situation of “running out of disk space”, I’m sure you will find the article helpful.

A logical volume functions like a normal partition — they have a filesystem such as Ext3, and a mount point. You can think of the volume group as a virtual hard disk. A logical volume is thus a virtual partition on your virtual hard disk.
