3 Setting Up The GlusterFS Client

client1.example.com:

On the client, we need to install fuse and GlusterFS. Instead of installing the libfuse2 package from the Debian repository, we install a patched version with better support for GlusterFS.

First we install the prerequisites again:

aptitude install sshfs build-essential flex bison byacc libdb4.6 libdb4.6-dev

Then we build fuse as follows (you can find the latest patched fuse version on ftp://ftp.zresearch.com/pub/gluster/glusterfs/fuse/):

cd /tmp
wget ftp://ftp.zresearch.com/pub/gluster/glusterfs/fuse/fuse-2.7.4glfs11.tar.gz
tar -zxvf fuse-2.7.4glfs11.tar.gz
cd fuse-2.7.4glfs11
./configure
make && make install

Afterwards we build GlusterFS (just like on the server)...

cd /tmp
wget http://ftp.gluster.com/pub/gluster/glusterfs/2.0/LATEST/glusterfs-2.0.1.tar.gz
tar xvfz glusterfs-2.0.1.tar.gz
cd glusterfs-2.0.1
./configure --prefix=/usr > /dev/null

make && make install
ldconfig
glusterfs --version

... and 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 server1.example.com # can be IP or hostname
  option remote-subvolume brick
end-volume

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

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

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

or

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

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

mount

client1:~# mount
/dev/mapper/vg0-root on / type ext3 (rw,errors=remount-ro)
tmpfs on /lib/init/rw type tmpfs (rw,nosuid,mode=0755)
proc on /proc type proc (rw,noexec,nosuid,nodev)
sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)
udev on /dev type tmpfs (rw,mode=0755)
tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev)
devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=620)
/dev/sda1 on /boot type ext3 (rw)
fusectl on /sys/fs/fuse/connections type fusectl (rw)
/etc/glusterfs/glusterfs.vol on /mnt/glusterfs type fuse.glusterfs (rw,max_read=131072,allow_other,default_permissions)
client1:~#

... and...

df -h

client1:~# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/vg0-root   19G  812M   17G   5% /
tmpfs                 253M     0  253M   0% /lib/init/rw
udev                   10M   80K   10M   1% /dev
tmpfs                 253M     0  253M   0% /dev/shm
/dev/sda1             471M   20M  427M   5% /boot
/etc/glusterfs/glusterfs.vol
                       29G  811M   27G   3% /mnt/glusterfs
client1:~#

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:

reboot

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

df -h

... and...

mount

a better fstab?

/etc/glusterfs/glusterfs.vol  /mnt/glusterfs  glusterfs  _netdev,defaults  0  0
