4.4. Red Hat Gluster Storage and Red Hat Enterprise Virtualization Integration

In the case that the Red Hat Gluster Storage server nodes and the Red Hat Enterprise Virtualization Hypervisors are present in the same data center, the servers of both types are listed for selection when you create a virtual machine or add a storage domain. Red Hat recommends that you create a separate data center for the Red Hat Gluster Storage server nodes.

When creating a Virtual Machine (VM) using a template, shard translator returned an incorrect file size. With stat-prefetch enabled, the incorrect file size is cached and served as a part of lookups/stat etc. As a result, VMs that were created using these templates were unbootable.

Workaround: Disable the stat-prefetch translator and re-create the VM. This ensures that the newly created VMs using the templates are bootable.
