How did you solved it? By switching to NFS only?
I removed the file on host1 (directly on the brick) and ran "gluster
volume heal engine full", which synced the file from host2 to host1.

seems like a vdsm failure in starting monitor the hosted engine storage domain.
Can you attach vdsm logs?
Logs are quite big for an email (6.8MB).
I attached the last entries which show the information for vm-start.
