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

BZ#1293412
When self-heal is required after an inode refresh, the file operation that triggered the heal process is served after the heal completes. This means that large files, such as virtual machine images, become unresponsive until the heal is complete and the file operation returns.
Workaround: Disable client-side self-heal to prevent file operations from blocking file access. Pending heals will still be tracked by the self-heal daemon.
# gluster volume set volname cluster.data-self-heal off
All images in data center displayed regardless of context
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.
