+A 3-way replicated common gluster meta-volume should be configured and is shared

Following are the steps to configure meta volume
Create a 3 way replicated meta volume in the master cluster with all three bricks from different nodes as follows.
```sh
- gluster volume create <meta_vol> replica 3 <host1>:<brick_path> <host2>:<brick_path> <host3>:<brick_path>
