====== GlusterFS ======

I use glusterfs to mirror a directory between cluster members.

<code>
cd /usr/src
wget -c ftp://gluster.org/pub/gluster/glusterfs/3.0/LATEST/glusterfs-3.*.tar.gz

aptitude install build-essential flex bison fuse-utils

tar xvzf glusterfs-3.*.tar.gz
cd glusterfs-3.*

./configure --sysconfdir=/etc --localstatedir=/var &amp;&amp; make -j2 &amp;&amp; make install

cd /etc/glusters
glusterfs-volgen -n data -r 1 -a 10.1.1.* server1:/data server2:/data

ln -s server1-data-export.vol glusterfsd.vol
ln -s data-tcp.vol glusterfs.vol

update-rc.d glusterfsd defaults
</code>
<strong>glusterfs.vol</strong>:

<code>
...
volume mirror-0
    type cluster/replicate
    subvolumes server1-1 server2-1
    option read-subvolume `hostname`-1
end-volume
...
</code>
<strong>/etc/fstab</strong>:

<code>
/etc/glusterfs/glusterfs.vol  /nas  glusterfs  defaults  0  0
</code>
