How to create a replicated glusterfs volume?

giraffelife

Do this from only one of the nodes in the gluster cluster.

Make the directory for the volume under the brick

gluster1> mkdir -p /data/brick1/gv0

Create the volume

gluster1> gluster volume create gv0 replica 2 server1:/data/brick1/gv0 ip-server2:/data/brick1/gv0
volume create: gv0: success: please start the volume to access data

Start the volume

gluster1> gluster volume start gv0
volume start: gv0: success

Check the status of the volume

gluster1> gluster volume info

The client can use either Gluster Native Client (FUSE) or NFSv3 see link: http://gluster.readthedocs.io/en/latest/Administrator Guide/Setting Up Clients/
Mount the gluster volume on a client.

gluster1> mount -t glusterfs server1:/gv0 /mnt

Create test file(s)

gluster1> pwd
/mnt
gluster1> touch myfile
gluster1> ls -l

Check the glusterfs mount points - on both nodes

gluster1> ls -la /data/brick1/gv0/
total 0
