4 Setting Up The GlusterFS Servers


apt-get install glusterfs-server

Next we create a few directories:

mkdir /data/export
mkdir /data/export-ns

Now we need to create the GlusterFS server configuration file /etc/glusterfs/glusterfsd.vol

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

volume posix
type storage/posix
option directory /data/export
volume locks
type features/locks
subvolumes posix
volume brick
type performance/io-threads
option thread-count 8
subvolumes locks
volume server
type protocol/server
option transport-type tcp
option auth.addr.brick.allow,
subvolumes brick

At last we can start the GlusterFS server:

/etc/init.d/glusterfs-server start


5 Setting Up The GlusterFS Client

In this case, MS Windows client need to have access to both nodes via SMB. That’s why, both nodes are working as GlusterFS server and client in same time.
On both nodes:


First we need to create client config file:

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

volume remote1
type protocol/client
option transport-type tcp
option remote-host
option remote-subvolume brick
volume remote2
type protocol/client
option transport-type tcp
option remote-host
option remote-subvolume brick
volume replicate
type cluster/replicate
subvolumes remote1 remote2
volume writebehind
type performance/write-behind
option window-size 1MB
subvolumes replicate
volume cache
type performance/io-cache
option cache-size 512MB
subvolumes writebehind

Done! Our cluster is set up. At last, we can mount the Gluster file system to /home directory with one of the following two commands:

glusterfs -f /etc/glusterfs/glusterfs.vol /home


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

You should now see the mounted share:

df -h

/dev/sdb1 9,9G 151M 9,2G 2% /data
/etc/glusterfs/glusterfs.vol 9,9G 151M 9,2G 2% /home

Like you can see, the same share is mounted twice. That's because GlusteFS server use /data directory, and GlusterFS client use /home directory.

Of course we want the shares gets mounted automatically when the servers start. The best way is to append following line into the /etc/rc.local (before the exit 0 line):

/bin/mount -t glusterfs /etc/glusterfs/glusterfs.vol /home


Testing …

on node2

... run ...

watch ls /home

on node1

... run ...

touch /home/test.file

on node2

... you should see ...

Every 2,0s: ls /home Tue Dec 25 13:12:30 2012

That’'s it, cluster already running. You may do some more tests, to see how GlusterFS works.
