GlusterFS : Dispersed Configuration2019/07/17 |
|
Configure Storage Clustering with GlusterFS.
For example, create a Dispersed volume with 6 Nodes.
Dispersed Volumes is based on Erasure Coding (EC).
|
+----------------------+ | +----------------------+
| [GlusterFS Server#1] |10.0.0.51 | 10.0.0.54| [GlusterFS Server#4] |
| node01.srv.world +----------+----------+ node04.srv.world |
| | | | |
+----------------------+ | +----------------------+
|
+----------------------+ | +----------------------+
| [GlusterFS Server#2] |10.0.0.52 | 10.0.0.55| [GlusterFS Server#5] |
| node02.srv.world +----------+----------+ node05.srv.world |
| | | | |
+----------------------+ | +----------------------+
|
+----------------------+ | +----------------------+
| [GlusterFS Server#3] |10.0.0.53 | 10.0.0.56| [GlusterFS Server#6] |
| node03.srv.world +----------+----------+ node06.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 [/glusterfs] directory for GlusterFS Configuration on all Nodes. |

root@node01:~# mkdir -p /glusterfs/dispersed |
| [3] | Configure Clustering like follows on a node. (it's OK on any node) |
