GlusterFS : Striping + Replication Setting2017/06/21 |
|
Configure Storage Clustering.
For example, create a Striping + 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 [/var/lib/glusterfs] directory for GlusterFS Configuration on all Nodes.

| [2] | Create a Directory for GlusterFS Volume on all Nodes. |
|
root@node01:~# mkdir -p /var/lib/glusterfs/strip-replica |
| [3] | Configure Clustering like follows on a node. (it's OK on any node) |

| [4] | If use NFS mount from Clients, Start required services first and also configure like follwos. |
