Creating An NFS-Like Standalone Storage Server With GlusterFS On Ubuntu 9.10
Author: Falko Timme
Follow me on Twitter
This tutorial shows how to set up a standalone storage server on Ubuntu 9.10. Instead of NFS, I will use GlusterFS here. The client system will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86_64 servers with SATA-II RAID and Infiniband HBA.
I do not issue any guarantee that this will work for you!
1 Preliminary Note
In this tutorial I use two systems, a server and a client:
- server1.example.com: IP address 192.168.0.100 (server)
- client1.example.com: IP address 192.168.0.101 (client)
Because we will run all the steps from this tutorial with root privileges, we can either prepend all commands in this tutorial with the string sudo, or we become root right now by typing
Both systems should be able to resolve the other system's hostname. If this cannot be done through DNS, you should edit the /etc/hosts file so that it looks as follows on both systems:
127.0.0.1 localhost.localdomain localhost 192.168.0.100 server1.example.com server1 192.168.0.101 client1.example.com client1 # The following lines are desirable for IPv6 capable hosts ::1 localhost ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters ff02::3 ip6-allhosts
(It is also possible to use IP addresses instead of hostnames in the following setup. If you prefer to use IP addresses, you don't have to care about whether the hostnames can be resolved or not.)
2 Setting Up The GlusterFS Server
GlusterFS is available as a package for Ubuntu 9.10, therefore we can install it as follows:
aptitude install glusterfs-server
should now show the GlusterFS version that you've just installed (2.0.2 in this case):
[email protected]:~# glusterfs --version
glusterfs 2.0.2 built on Jun 29 2009 23:49:59

Next we create a few directories:
Now we create the GlusterFS server configuration file /etc/glusterfs/glusterfsd.vol (we make a backup of the original /etc/glusterfs/glusterfsd.vol file first) which defines which directory will be exported (/data/export) and what client is allowed to connect (192.168.0.101 = client1.example.com):
cp /etc/glusterfs/glusterfsd.vol /etc/glusterfs/glusterfsd.vol_orig
cat /dev/null > /etc/glusterfs/glusterfsd.vol
volume posix type storage/posix option directory /data/export end-volume volume locks type features/locks option mandatory-locks on subvolumes posix end-volume volume brick type performance/io-threads option thread-count 8 subvolumes locks end-volume volume server type protocol/server option transport-type tcp option auth.addr.brick.allow 192.168.0.101 # Edit and add list of allowed clients comma separated IP addrs(names) here subvolumes brick end-volume
Please note that it is possible to use wildcards for the IP addresses (like 192.168.*) and that you can specify multiple IP addresses separated by comma (e.g. 192.168.0.101,192.168.0.102).
Afterwards we start the GlusterFS server:
