|
Configure Storage Clustering.
For example, create a Replication volume with 2 servers.
This example shows to use 2 servers but it's possible to use more than 3 servers.
|
+----------------------+ | +----------------------+
| [GlusterFS Server#1] |10.0.0.51 | 10.0.0.52| [GlusterFS Server#2] |
| node01.srv.world +----------+----------+ node02.srv.world |
| | | |
+----------------------+ +----------------------+
|
|
It is recommended to use partitions for GlusterFS volumes which are different from the / partition.
The environment on this example is set as that sdb1 is mounted on /glusterfs directory for GlusterFS Configuration on all Nodes.

|
[root@node01 ~]# mkdir /glusterfs/replica |
| [3] | Configure Clustering like follows on a node. (it's OK on any node) |
