Extending an LVM volume

The following commands adds a new partition to an existing lvm volume. Tested on Ubuntu 10.04. First, find out your volume name using: sudo vgdisplay

1. sudo cfdisk /dev/sda <- create the new partition in free space here. note the partition number (sdaX).
2. sudo pvcreate /dev/sdaX <- creates a new physical volume with this new partition (X is the partition number)
3. vgextend VOLUME /dev/sdaX
4. sudo vgdisplay <- find out the amount of free space in lvm
5. sudo lvextend -L+1G /dev/mapper/VOLUME-root
6. sudo resize2fs /dev/mapper/VOLUME-root
7. df -h
