Chapter 5. Managing Red Hat Gluster Storage Servers and Volumes using Red Hat Virtualization Manager

You can create and configure Red Hat Gluster Storage volumes using Red Hat Virtualization Manager 3.3 or later by creating a separate cluster with the Enable Gluster Service option enabled.

Note

Red Hat Gluster Storage nodes must be managed in a separate cluster to Red Hat Virtualization hosts. If you want to configure combined management of virtualization hosts and storage servers, see the Red Hat Hyperconverged Infrastructure documentation: https://access.redhat.com/documentation/en-us/red_hat_hyperconverged_infrastructure/1.0/html/deploying_red_hat_hyperconverged_infrastructure/
A volume is a logical collection of bricks where each brick is an export directory on a server in the trusted storage pool. Most of the management operations for Red Hat Gluster Storage happen on these volumes. You can use Red Hat Virtualization Manager to create and start new volumes featuring a single global namespace.

Note

With the exception of the volume operations described in this section, all other Red Hat Gluster Storage functionalities must be executed from the command line.
