GlusterFS Client
Software
Installation
Install the glusterfs client.
apt-get install glusterfs-client
Mount Point
Create the mount point.
mkdir /srv/www
Volume File
A regular fstab entry with an IP-address for one of the GlusterFS servers can be added, but if that specific server is down when we attempt to mount the GlusterFS volume, then it will fail. Instead we will create a file that describes how to mount the volume.
mkdir /etc/glusterfs
Create the file /etc/glusterfs/www.vol and add the servers.
volume remote1 type protocol/client option transport-type tcp option remote-host gluster01 option remote-subvolume /srv/www/brick end-volume volume remote2 type protocol/client option transport-type tcp option remote-host gluster02 option remote-subvolume /srv/www/brick end-volume volume remote3 type protocol/client option transport-type tcp option remote-host gluster03 option remote-subvolume /srv/www/brick end-volume volume remote4 type protocol/client option transport-type tcp option remote-host gluster04 option remote-subvolume /srv/www/brick end-volume volume replicate type cluster/replicate subvolumes remote1 remote2 remote3 remote4 end-volume volume writebehind type performance/write-behind option window-size 1MB subvolumes replicate end-volume volume cache type performance/io-cache option cache-size 64MB subvolumes writebehind end-volume
Note that if one of the GlusterFS servers is an arbiter, then it shold also be added to the volume file.

/etc/glusterfs/www.vol /srv/www glusterfs defaults,_netdev,rw 0 0
