# Prerequisites

Before you can start using CTDB you must first install and configure a bunch of linux boxes.
After that you need to install and configure a cluster filesystem and mount that cluster filesystem on all the linux boxes that will form your cluster.
We have primarily used the GPFS filesystem for our testing but any cluster filesystem should work as long as it provides correct file locking.

# Other cluster filesystems

While we primarily test with GPFS, CTDB should work with almost any other cluster filesystem as well.
Please let us know your experiences in using other cluster filesystems.
