8.1.1. Adding Red Hat Gluster Storage Nodes

Add Red Hat Gluster Storage nodes to Gluster-enabled clusters and incorporate GlusterFS volumes and bricks into your Red Hat Enterprise Virtualization environment.
This procedure presumes that you have a Gluster-enabled cluster of the appropriate Compatibility Version and a Red Hat Gluster Storage node already set up. For information on setting up a Red Hat Gluster Storage node, see the Red Hat Gluster Storage Installation Guide. For more information on the compatibility matrix, see the Configuring Red Hat Enterprise Virtualization with Red Hat Storage Guide.

Procedure 8.1. Adding a Red Hat Gluster Storage Node

  1. Click the Hosts resource tab to list the hosts in the results list.
  2. Click New to open the New Host window.
  3. Use the drop-down menus to select the Data Center and Host Cluster for the Red Hat Gluster Storage node.
  4. Enter the Name, Address, and SSH Port of the Red Hat Gluster Storage node.
  5. Select an authentication method to use with the Red Hat Gluster Storage node.
    • Enter the root user's password to use password authentication.
    • Copy the key displayed in the SSH PublicKey field to /root/.ssh/authorized_keys on the Red Hat Gluster Storage node to use public key authentication.
  6. Click OK to add the node and close the window.
You have added a Red Hat Gluster Storage node to your Red Hat Enterprise Virtualization environment. You can now use the volume and brick resources of the node in your environment.

8.1.2. Removing a Red Hat Gluster Storage Node

Remove a Red Hat Gluster Storage node from your Red Hat Enterprise Virtualization environment.
