Block storage node (Optional)¶

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

   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.
