Being a distributed filesystem, Gluster require multiple servers to work. A Gluster filesystem is first achieved by creating a cluster of servers called Trusted Server Pool.

These servers need to have GlusterFS server package installed and configured before joining together. You can configure the Trusted Server Pool for GlusterFS from the terminal using the gluster tool.

Steps to create trusted server pool for GlusterFS:

  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
