GlusterFS 5 : Replication Configuration2018/12/13

 
Configure Storage Clustering with GlusterFS.
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.

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.

[2] Create a Directory for GlusterFS Volume on all Nodes.
[root@node01 ~]#
mkdir -p /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: 3dc44051-4139-4ff1-be53-329d4711afeb
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
