GlusterFS : Striping + Replication Setting
2017/06/21 |
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) |
# probe the node root@node01:~# gluster peer probe node02 peer probe: success. root@node01:~# gluster peer probe node03 peer probe: success. root@node01:~# gluster peer probe node04 peer probe: success. # show status root@node01:~# gluster peer status Number of Peers: 3 Hostname: node02 Uuid: a39156f3-32cb-451e-9e34-08ce504d72bb State: Peer in Cluster (Connected) Hostname: node03 Uuid: b86b98e4-12b6-4581-984d-da420d7b3bbe State: Peer in Cluster (Connected) Hostname: node04 Uuid: 6a1fb91a-f483-48c7-8dc7-0f2ac4d8db94 State: Peer in Cluster (Connected) # create volume root@node01:~# gluster volume create vol_strip-replica stripe 2 replica 2 transport tcp \ node01:/var/lib/glusterfs/strip-replica \ node02:/var/lib/glusterfs/strip-replica \ node03:/var/lib/glusterfs/strip-replica \ node04:/var/lib/glusterfs/strip-replica volume create: vol_strip-replica: success: please start the volume to access data # start volume root@node01:~# gluster volume start vol_strip-replica volume start: vol_strip-replica: success # show volume info root@node01:~# gluster volume info Volume Name: vol_strip-replica Type: Striped-Replicate Volume ID: 67bf7ce3-d990-48c6-8998-47ce7f032209 Status: Created Snapshot Count: 0 Number of Bricks: 1 x 2 x 2 = 4 Transport-type: tcp Bricks: Brick1: node01:/var/lib/glusterfs/strip-replica Brick2: node02:/var/lib/glusterfs/strip-replica Brick3: node03:/var/lib/glusterfs/strip-replica Brick4: node04:/var/lib/glusterfs/strip-replica Options Reconfigured: transport.address-family: inet performance.readdir-ahead: on nfs.disable: on |
[4] | If use NFS mount from Clients, Start required services first and also configure like follwos. |
root@node01:~# gluster volume set vol_strip-replica nfs.disable off volume set: success |
