Enabling VM leases could be an answer to this. Will test tomorrow.

Hi All,

I have the following issue with the HA behavior of oVirt 4.1 and need to check with you if there is any work around from your experience.

I have 3 servers (A, B, C) with hosted engine in self hosted setup on top gluster with replica 3 + 1 arbiter. All good except one point:

The hosts have been configured with power management using IPMI (server iLO).

If I disconnect power from one host (say C) (or disconnect all network cables of the host) the two other hosts go to a loop where they try to verify the status of the host C by issuing power management commands to the host C. Since power of host is off the server iLO does not respond on the network and the power management of host C fails, leaving the VMs that were running on the host C in an unknown state and they are never restarted to the other hosts. 

Is there any fencing option to change this behavior so as if both available hosts fail to do power management of the unresponsive host to decide that the host is down and to restart the VMs of that host to the other available hosts.

I could also add additional power management through UPS to avoid this issue but this is not currently an option and I am interested to see if this behavior can be tweaked.

Thanx,

Alex
