Installing Gluster

++++++++++++++++++

For Gluster integration, Ganeti requires that ``mount.glusterfs`` is

installed on each and every node. On Debian Wheezy and newer, you can

satisfy this requirement with the ``glusterfs-client`` package; see

`this guide

<http://gluster.org/community/documentation/index.php/Gluster_3.2:_Installing_the_Gluster_Native_Client>`_

for details.

KVM userspace access

~~~~~~~~~~~~~~~~~~~~

If your cluster uses a sufficiently new version of KVM (you will need at

least QEMU 1.3 with Gluster support compiled in), you can take advantage

of KVM's native support for gluster in order to have better performance

and avoid potential deadlocks in low memory scenarios.

Please be aware that QEMU 1.3 was released in December 3, 2012, and as

such this feature is not available out of the box in any distribution

older than Ubuntu 13.04; this excludes Ubuntu 12.04 LTS and Debian

Wheezy.
