Resize a Xen disk image


Its as easy as appending zeros to the disk image.

Here I append 10 GB to disk.img. Please note that resize2fs will, of course, only work if your disk contains a ext2/3 partition.

cd /var/lib/xend/domains/domain/
dd if=/dev/zero bs=1024 count=10000000 >> disk.img
resize2fs -f disk.img
