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.

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]. |
