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¶
- Set the hostname of the node to - block1.
- Edit the - /etc/hostsfile 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/hostsfile 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. 
- Reboot the system to activate the changes.
