Hi Denis,
I receive permission denied as below:

When I shutdown host3 then no split brain is reported from the remaining two hosts. When I power up host3 then I receive the mentioned split brain and host3 logs the following at ovirt-hosted-engine-ha/agent.log

Hi All,
I have a 3 node ovirt 4.1 setup. I lost one node due to raid controller issues. Upon restoration I have the following split brain, although the hosts have mounted the storage domains:

It is definitely on gluster side. You could try to use
gluster volume heal engine split-brain latest-mtime /e1c80750-b880-49 5e-9609-b8bc7760d101/ha_agent
I also added gluster developers to that thread, so they may provide you with better advices.
