If the engine imported the hosted-engine storage domain in the past, that storage domain is in the engine DB with the wrong path. If you bring down everything and reboot your hosts, ovirt-ha-agent will mount the hosted-engine-storage domain with the new path under hosted- engine.conf. At this point ovirt-ha-agent can start the engine VM. When the engine will come up it will try to mount all the storage domain in the datacenter as for regular hosts. This will mean that it will try to remount also the hosted-engine storage domain (cause the domain uuid is the same!) from the old path since it's still configured like that in the engine DB. > I think the only way is to reinstall Hosted VM from scratch.
