GlusterFS 8 : Distributed + Replication2021/04/05 |
|
Configure Storage Clustering with GlusterFS.
For example, Create a Distributed + Replication volume with 6 Nodes.
Also Configure Arbiter Volume in order to avoid Split Brain.

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]. |

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