Block storage node (Optional)

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:
    • Network mask: (or /24)
    • Default gateway:

Configure name resolution

  1. Set the hostname of the node to block1.

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

    # controller       controller
    # compute1       compute1
    # block1       block1
    # object1       object1
    # object2       object2


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


    To reduce complexity of this guide, we add host entries for optional services regardless of whether you choose to deploy them.

  3. Reboot the system to activate the changes.
