2 node hyperconverged gluster is definitively a bad idea since it's not
going to protect you from split brains.
Please choose 1 or 3 but not 2.

Without any logs it's difficult to guess what really happened but I think
that it could be related to the two nodes approach which is explicitly
prevented.

This simply means that ovirt-ha-agents fails to communicate (in order to
send a ping to check network connectivity) with ovirt-ha-broker over a unix
domain socket.
'[Errno 2] No such file or directory' means that the socket is closed on
ovirt-ha-broker side: you can probably see why checking
/var/log/ovirt-hosted-engine-ha/broker.log but if didn't successfully
completed the setup this is not surprising me and I strongly suggest to
correctly complete the deployment before trying anything else.
