Creating An NFS-Like Standalone Storage Server With GlusterFS On Ubuntu 9.10 - Page 2

3 Setting Up The GlusterFS Client

On the client, we can install the GlusterFS client as follows:

aptitude install glusterfs-client glusterfs-server

Then we create the following directory:

mkdir /mnt/glusterfs

Next we create the file /etc/glusterfs/glusterfs.vol (we make a backup of the original /etc/glusterfs/glusterfs.vol file first):

cp /etc/glusterfs/glusterfs.vol /etc/glusterfs/glusterfs.vol_orig
cat /dev/null > /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...


root@client1:~# mount
/dev/mapper/client1-root on / type ext4 (rw,errors=remount-ro)
proc on /proc type proc (rw)
none on /sys type sysfs (rw,noexec,nosuid,nodev)
none on /sys/fs/fuse/connections type fusectl (rw)
none on /sys/kernel/debug type debugfs (rw)
none on /sys/kernel/security type securityfs (rw)
udev on /dev type tmpfs (rw,mode=0755)
none on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620)
none on /dev/shm type tmpfs (rw,nosuid,nodev)
none on /var/run type tmpfs (rw,nosuid,mode=0755)
none on /var/lock type tmpfs (rw,noexec,nosuid,nodev)
none on /lib/init/rw type tmpfs (rw,nosuid,mode=0755)
/dev/sda5 on /boot type ext2 (rw)
/etc/glusterfs/glusterfs.vol on /mnt/glusterfs type fuse.glusterfs (rw,max_read=131072,allow_other,default_permissions)

... and...

df -h

root@client1:~# df -h
Filesystem            Size  Used Avail Use% Mounted on
                       29G  808M   26G   3% /
udev                  248M  152K  247M   1% /dev
none                  248M     0  248M   0% /dev/shm
none                  248M   36K  248M   1% /var/run
none                  248M     0  248M   0% /var/lock
none                  248M     0  248M   0% /lib/init/rw
/dev/sda5             228M   15M  202M   7% /boot
                       18G  807M   16G   5% /mnt/glusterfs

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...

Its best to use 'sudo -s'   instead of 'sudo su' 

 see the following URL for the logic.

Save yourself some typing chars.

Instead of cat /dev/null > /etc/glusterfs/glusterfsd.vol


 > /etc/glusterfs/glusterfsd.vol

 Instead of cp /etc/glusterfs/glusterfsd.vol /etc/glusterfs/glusterfsd.vol_orig


cp /etc/glusterfs/glusterfsd.vol{,_orig}

if I need more space in my storage as I add more nodes using this configuration?
tank in advance!

What is the export-ns directory for? I saw the use of a ns-dir in other tutorials without any clue of it's use. But in your example it doesn't even get referenced anywhere.

The glusterfs-volgen script from upstream GlusterFS doesn't use extra ns-dirs neither.
