gistfile1.txt
Backup the File based image firstly, making sure it is not mounted nor running as a xen domU.
dd if=/dev/zero of=file.img bs=1M conv=notrunc count=1 seek=2000
#This resizes the file.img to 2GB.
losetup /dev/loop1 file.img
#loop1 had to be used as xen was already running a different domU via loop0.
e2fsck -f /dev/loop1
resize2fs /dev/loop1
e2fsck -f /dev/loop1
losetup -d /dev/loop1
