If you want to use a loopback device instead of another partition, follow these instructions.
#. `mkdir /srv`
#. `dd if=/dev/zero of=/srv/swift-disk bs=1024 count=0 seek=1000000`
(modify seek to make a larger or smaller partition)
#. `truncate -s 1GB /srv/swift-disk`
(modify size to make a larger or smaller partition)
#. `mkfs.xfs -i size=1024 /srv/swift-disk`
#. Edit `/etc/fstab` and add
