Create LVM Volume With Remaining Space

When you install Ubuntu with the default partitions, for some reason, it uses only half of the available disk. If you forget to create a home/var/whatever partition during the install process, you can do it after the fact. To use all of the remaining space in a volume group, you can use the following syntax:

lvcreate -l 100%VG -n home-lv ubuntu-vg

Of course, this is all in the man pages. This is just a quick note because I always forget the syntax.
