Steps to create GlusterFS storage cluster:

  1. Launch terminal.
  2. Open /etc/hosts file on all nodes using your preferred text editor.
    $ sudo vi /etc/hosts
    [sudo] password for user:
  3. Add static DNS name and optionally alias for all cluster nodes.
    #IP               Name                   Alias
    192.168.111.70    node1.gluster.local    node1
    192.168.111.71    node2.gluster.local    node2
  4. Ping each nodes for all node to test if configuration is successful and nodes are reachable via network.
    $ ping -c3 node1
    PING node1.gluster.local (192.168.111.70) 56(84) bytes of data.
    64 bytes from node1.gluster.local (192.168.111.70): icmp_seq=1 ttl=64 time=0.018 ms
    64 bytes from node1.gluster.local (192.168.111.70): icmp_seq=2 ttl=64 time=0.020 ms
    64 bytes from node1.gluster.local (192.168.111.70): icmp_seq=3 ttl=64 time=0.035 ms
    
    --- node1.gluster.local ping statistics ---
    3 packets transmitted, 3 received, 0% packet loss, time 2029ms
    rtt min/avg/max/mdev = 0.018/0.024/0.035/0.007 ms
    $ ping -c3 node2.gluster.local
    PING node2.gluster.local (192.168.111.71) 56(84) bytes of data.
    64 bytes from node2.gluster.local (192.168.111.71): icmp_seq=1 ttl=64 time=1.72 ms
    64 bytes from node2.gluster.local (192.168.111.71): icmp_seq=2 ttl=64 time=0.626 ms
    64 bytes from node2.gluster.local (192.168.111.71): icmp_seq=3 ttl=64 time=0.410 ms
    
    --- node2.gluster.local ping statistics ---
    3 packets transmitted, 3 received, 0% packet loss, time 2015ms
    rtt min/avg/max/mdev = 0.410/0.919/1.722/0.574 ms
  5. Create a Trusted Pool (Storage Cluster) from the first node by probing for all the other nodes.
    $ sudo gluster peer probe node2
    peer probe: success.
  6. Check if peers were successfully added from any node.
    $ sudo gluster peer status
    Number of Peers: 1
    
    Hostname: node2
    Uuid: 6770f88c-9ec5-4cf8-b9f5-658fa17b6bdc
    State: Peer in Cluster (Connected)
  7. Check Trusted Pool status from any node.
    $ sudo gluster pool list
    UUID					Hostname 	State
    6770f88c-9ec5-4cf8-b9f5-658fa17b6bdc	node2    	Connected 
    bca7490b-64c2-46d1-ae9a-4577cc03625f	localhost	Connected
