Configure Storage Clustering with GlusterFS.

For example, create a distributed volume with 2 Nodes.

This example shows to use 2 Nodes but it’s possible to use more than 3 Nodes.

|
+----------------------+ | +----------------------+
| [GlusterFS Server#1] |10.0.0.51 | 10.0.0.52| [GlusterFS Server#2] |
| node01.srv.world +----------+----------+ node02.srv.world |
| | | |
+----------------------+ +----------------------+

 file1, file3 ... file2, file4 ...

It is strongly recommended to use partitions for GlusterFS volumes that are different from the / partition. On this example, it shows settings on the environment that all nodes has [sdb1] and mount it to [/glusterfs].

Install GlusterFS Server on All Nodes, refer to here .

Create a Directory for GlusterFS Volume on all Nodes.

[root@node01 ~]# mkdir -p /glusterfs/distributed

Configure Clustering like follows on a node. (it’s OK on any node)

# probe nodes
[root@node01 ~]# gluster peer probe node02
peer probe: success.
# confirm status
[root@node01 ~]# gluster peer status
Number of Peers: 1

Hostname: node02
Uuid: 441975fb-318f-40ca-a28f-842a7472a7c7
State: Peer in Cluster (Connected)
# create volume
[root@node01 ~]# gluster volume create vol_distributed transport tcp \ node01:/glusterfs/distributed \ node02:/glusterfs/distributed
volume create: vol_distributed: success: please start the volume to access data
# start volume
[root@node01 ~]# gluster volume start vol_distributed
volume start: vol_distributed: success
# confirm volume info
[root@node01 ~]# gluster volume info
