+====== glusterfs ======
+  * [[Filesystems]]
+  * [[mkfs.xfs]]
+  * uses NFS
+  * very few dependencies
+  * can run on top of any filesystem
+  * automatic failover
+Things I'm not sure about:
+  * no-metadata server architecture
+  * noted some performance slowdown with Samba
+  * using any filesystem means that they're not taking advantage of some situations, or may be not using a large featureset; generally, it makes me think this is more of a hobby setup ("we can run anywhere!") than a production one ("use these for best practices")
+==== Setup ====
+  * [[http://gluster.readthedocs.org/en/latest/Quick-Start-Guide/Quickstart/|Quick Start Guide]]
+Create an format a partition for the node:
+<code>
+mkfs.xfs -i size=512 /dev/sdb1
+mount /dev/sdb1 /var/gluster
+mkdir /var/gluster/brick
+</code>
+Add an entry to ''/etc/fstab'' for each server:
+<code>
+/dev/sdb1 /var/gluster/brick1 xfs noatime 0 0
+</code>
+Mount the drive, and start the glusterfs daemon:
+<code>
+mount -a
+/etc/init.d/glusterd start
+</code>
+Have each server probe each other. On server1:
+<code>
+gluster peer probe server2
+</code>
+On server2:
+<code>
+gluster peer probe server1
+</code>
+On both servers, create the gluster volume directory:
+<code>
+mkdir /var/gluster/brick1/gv0
+</code>
+Then, from either server, create the gluster volume:
+<code>
+gluster volume create gv0 replica 2 server1:/var/gluster/gv0 server2:/var/gluster/gv0
+gluster volume start gv0
+</code>
+You can check the status of the volume on either server:
+<code>
+gluster volume info
+</code>
+<code>
+Volume Name: gv0
+Type: Replicate
+Status: Started
+Number of Bricks: 2
+Transport-type: tcp
+Bricks:
+Brick1: gluster1:/var/gluster/brick1/gv0
+Brick2: gluster2:/var/gluster/brick1/gv0
+</code>
+If the status is not started, check the logs in ''/var/log/glusterfs'', usually in ''etc-glusterfs-glusterd.vol.log''.
