Chapter 5. Recommended Best Practices and Troubleshooting

Enable the server side quorum at all times for the Red Hat Storage volumes hosting virtual machine images. For more information, see section, Configuring Server-Side Quorum in the Red Hat Storage Administration Guide
Red Hat Storage Volumes that serve as Red Hat Enterprise Virtualization Master Storage Domain contain SANLocks and have the Red Hat Storage volume profile set to virt. This enables the Client Side Quorum for 2-way Automatic File Replication and avoids the inconsistency problems for Multiple Writer situations. For more information see section, Configuring Client-Side Quorum in the Red Hat Storage Administration Guide
Disable the client side quorum for Red Hat Storage volumes that host Virtual Machines images for high-availability with 2-way replication.
