Description Byron Gravenorst 2017-02-15 02:52:49 UTC 
High availability could previously not be enabled for virtual machines in Hyper-converged mode. Previous fencing policies ignored Gluster processes. But in Hyper-converged mode, fencing policies are required to ensure that a host is not fenced if there is a brick process running, or to ensure no loss of quorum when shutting down the host with an active brick.

The following fencing policies have been added to Hyper-converged clusters:
- SkipFencingIfGlusterBricksUp: Fencing will be skipped if bricks are running and can be reached from other peers.
- SkipFencingIfGlusterQuorumNotMet: Fencing will be skipped if bricks are running and shutting down the host will cause loss of quorum

Virtual machine high availability can be tested by enabling power management on hyper-converged nodes.
