GlusterFS 6 : Dispersed Configuration2019/05/30 |
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. |

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