There is a new version of this tutorial available for CentOS 6.3.

3 Setting Up The GlusterFS Client

GlusterFS isn't available as a package for CentOS 5.4, therefore we have to build it ourselves. First we install the prerequisites:

yum groupinstall 'Development Tools'
yum groupinstall 'Development Libraries'
yum install libibverbs-devel fuse-devel

Then we load the fuse kernel module...

modprobe fuse

... and create the file /etc/rc.modules with the following contents so that the fuse kernel module will be loaded automatically whenever the system boots:

vi /etc/rc.modules
modprobe fuse

Make the file executable:

chmod +x /etc/rc.modules 

Then we download the GlusterFS 2.0.9 sources (please note that this is the same version that is installed on the server!) and build GlusterFS as follows:

cd /tmp
tar xvfz glusterfs-2.0.9.tar.gz
cd glusterfs-2.0.9

At the end of the ./configure command, you should see something like this:

GlusterFS configure summary
FUSE client        : yes
Infiniband verbs   : yes
epoll IO multiplex : yes
Berkeley-DB        : yes
libglusterfsclient : yes
argp-standalone    : no

make && make install

Check the GlusterFS version afterwards (should be 2.0.9):

glusterfs --version

[[email protected] glusterfs-2.0.9]# glusterfs --version
glusterfs 2.0.9 built on Mar 1 2010 15:58:06
Repository revision: v2.0.9
Copyright (c) 2006-2009 Gluster Inc. <>
You may redistribute copies of GlusterFS under the terms of the GNU General Public License.
[[email protected] glusterfs-2.0.9]#

Then we create the following two directories:

mkdir /mnt/glusterfs
mkdir /etc/glusterfs

Next we create the file /etc/glusterfs/glusterfs.vol:

vi /etc/glusterfs/glusterfs.vol
volume remote
  type protocol/client
  option transport-type tcp
  option remote-host # can be IP or hostname
  option remote-subvolume brick

volume writebehind
  type performance/write-behind
  option window-size 4MB
  subvolumes remote

volume cache
  type performance/io-cache
  option cache-size 512MB
  subvolumes writebehind

Make sure you use the correct server hostname or IP address in the option remote-host line!

That's it! Now we can mount the GlusterFS filesystem to /mnt/glusterfs with one of the following two commands:

glusterfs -f /etc/glusterfs/glusterfs.vol /mnt/glusterfs


mount -t glusterfs /etc/glusterfs/glusterfs.vol /mnt/glusterfs

You should now see the new share in the outputs of...


[[email protected] ~]# mount
/dev/mapper/VolGroup00-LogVol00 on / type ext3 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
/dev/sda1 on /boot type ext3 (rw)
tmpfs on /dev/shm type tmpfs (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
glusterfs#/etc/glusterfs/glusterfs.vol on /mnt/glusterfs type fuse (rw,allow_other,default_permissions,max_read=131072)
[[email protected] ~]#

... and...

df -h

[[email protected] ~]# df -h
Filesystem            Size  Used Avail Use% Mounted on
                       29G  2.2G   25G   9% /
/dev/sda1              99M   13M   82M  14% /boot
tmpfs                 187M     0  187M   0% /dev/shm
                       28G  2.3G   25G   9% /mnt/glusterfs
[[email protected] ~]#

Instead of mounting the GlusterFS share manually on the client, you could modify /etc/fstab so that the share gets mounted automatically when the client boots.

Open /etc/fstab and append the following line:

vi /etc/fstab  
/etc/glusterfs/glusterfs.vol  /mnt/glusterfs  glusterfs  defaults  0  0

To test if your modified /etc/fstab is working, reboot the client:


After the reboot, you should find the share in the outputs of...

df -h 

... and...
