GlusterFS : Striping + Replication
2016/06/05 |
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 /glusterfs directory for GlusterFS Configuration on all Nodes. |

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