|
Configure GlusterFS Storage Cluster.
For example, create a Distributed + Replication volume with 4 servers.
|
+----------------------+ | +----------------------+
| [GlusterFS Server#1] |10.0.0.51 | 10.0.0.52| [GlusterFS Server#2] |
| node01.srv.world +----------+----------+ node02.srv.world |
| | | | |
+----------------------+ | +----------------------+
|
+----------------------+ | +----------------------+
| [GlusterFS Server#3] |10.0.0.53 | 10.0.0.54| [GlusterFS Server#4] |
| node03.srv.world +----------+----------+ node04.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. |
