Hi Guys,
I need help with my ovirt Hosted-Engine HA setup. I am running on 2
ovirt hosts and 2 gluster nodes with replicated volumes. i already have
VMs running on my hosts and they can migrate normally once i for example
power off the host that they are running on. the problem is that the
engine can't migrate once i switch off the host that hosts the engine.
oVirt 3.4.3-1.el6
KVM 0.12.1.2 - 2.415.el6_5.10
LIBVIRT libvirt-0.10.2-29.el6_5.9
VDSM vdsm-4.14.17-0.el6
right now, i have this result from hosted-engine --vm-status.

restarting ha-broker and ha-agent normalizes the status but eventually
it would become "false" and then return to the result above. hope you
guys could help me with this.
Hi Jaicel,
please attach agent.log and broker.log from the host where you trying to
run hosted-engine --vm-status. I have a feeling that you ran into a
known problem on gluster - stalled file descriptor, in that case the
only known solution at this time is to restart the broker & agent as you
have already found out.
Adding Niels and gluster-devel to troubleshoot from Gluster NFS perspective.
Thanks,
Vijay
