Block storage node (Optional)

If you want to deploy the Block Storage service, configure one additional storage node.

Configure network interfaces

  • Configure the management interface:

    • IP address: 10.0.0.41

    • Network mask: 255.255.255.0 (or /24)

    • Default gateway: 10.0.0.1

Configure name resolution

  1. Set the hostname of the node to block1.

  2. Edit the /etc/hosts file to contain the following:

    # controller
    10.0.0.11       controller
    
    # compute1
    10.0.0.31       compute1
    
    # block1
    10.0.0.41       block1
    
    # object1
    10.0.0.51       object1
    
    # object2
    10.0.0.52       object2
    

    Warning

    Some distributions add an extraneous entry in the /etc/hosts file that resolves the actual hostname to another loopback IP address such as 127.0.1.1. You must comment out or remove this entry to prevent name resolution problems. Do not remove the 127.0.0.1 entry.

    Note

    This guide includes host entries for optional services in order to reduce complexity should you choose to deploy them.

  3. Reboot the system to activate the changes.
