GlusterFS : Distributed Configuration

Configure Storage Clustering with GlusterFS. For example, create a distributed volume with 2 Nodes. This example shows to use 2 Nodes but it's possible to use more than 3 Nodes. | +----------------------+ | +----------------------+ | [GlusterFS Server#1] |10.0.0.51 | 10.0.0.52| [GlusterFS Server#2] | | node01.srv.world +----------+----------+ node02.srv.world | | | | | +----------------------+ +----------------------+ ⇑ ⇑ file1, file3 ... file2, file4 ...

	It is strongly recommended to use partitions for GlusterFS volumes that are different from the / partition. On this example, it shows settings on the environment that all nodes has [sdb1] and mount it to [/glusterfs].
[1]	Install GlusterFS Server on All Nodes, refer to here.
[2]	Create a Directory for GlusterFS Volume on all Nodes.

root@node01:~#  mkdir -p /glusterfs/distributed

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

# probe nodes root@node01:~#  gluster peer probe node02 peer probe: success. # confirm status root@node01:~#  gluster peer status Number of Peers: 1 Hostname: node02 Uuid: f11a43b8-6d3d-4ae7-92ed-1f633699515c State: Peer in Cluster (Connected) # create volume root@node01:~#  gluster volume create vol_distributed transport tcp \ node01:/glusterfs/distributed \ node02:/glusterfs/distributed volume create: vol_distributed: success: please start the volume to access data # start volume root@node01:~#  gluster volume start vol_distributed volume start: vol_distributed: success # confirm volume info root@node01:~#  gluster volume info Volume Name: vol_distributed Type: Distribute Volume ID: d4fc8b6c-a7c4-452e-a969-5b981bdaa363 Status: Started Snapshot Count: 0 Number of Bricks: 2 Transport-type: tcp Bricks: Brick1: node01:/glusterfs/distributed Brick2: node02:/glusterfs/distributed Options Reconfigured: storage.fips-mode-rchecksum: on transport.address-family: inet nfs.disable: on
