Configure Storage Clustering

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.server.world +----------+----------+ node02.server.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.
[1]	Install GlusterFS Server on All Nodes, refer to here.
[2]	Create a Directory for GlusterFS Volume on all Nodes.

[root@node01 ~]#  mkdir /glusterfs/replica

[3]	Configure Clustering like follows on a node. (it's OK on any node)

# probe the node [root@node01 ~]#  gluster peer probe node02  peer probe: success. # show status [root@node01 ~]#  gluster peer status  Number of Peers: 1 Hostname: node02 Uuid: 2ca22769-28a1-4204-9957-886579db2231 State: Peer in Cluster (Connected) # create volume [root@node01 ~]#  gluster volume create vol_replica replica 2 transport tcp \ node01:/glusterfs/replica \ node02:/glusterfs/replica  volume create: vol_replica: success: please start the volume to access data # start volume [root@node01 ~]#  gluster volume start vol_replica  volume start: vol_replica: success # show volume info [root@node01 ~]#  gluster volume info  Volume Name: vol_replica Type: Replicate Volume ID: 0d5d5ef7-bdfa-416c-8046-205c4d9766e6 Status: Started Number of Bricks: 1 x 2 = 2 Transport-type: tcp Bricks: Brick1: node01:/glusterfs/replica Brick2: node02:/glusterfs/replica Options Reconfigured: performance.readdir-ahead: on
