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)

#. `fallocate /srv/swift-disk -l 100MB`

(modify length to make a larger or smaller partition)

#. `mkfs.xfs -i size=1024 /srv/swift-disk`

#. Edit `/etc/fstab` and add

`/srv/swift-disk /mnt/sdb1 xfs loop,noatime,nodiratime,nobarrier,logbufs=8 0 0`
