Basically that after the first host installation+deploy (from the CLI), after I enable the gluster management in the cluster, I have to manually restart vdsmd on host1 to be able to install the other hosts. But maybe I should just wait more time for vdmsd catch up with everything, I don't know. Then I have some other problem like a ghost VM stuck on one host after moving the host to maintenance and the VM (the hosted-engine, the only one running in the whole cluster) being correctly migrated to another host, solved only by a manual reboot of the whole host (and consequent HE fencing of the host). I must say that that particular host is giving ECC correction errors in one DIMM, so maybe it could just be an HW related problem. > >> Deploy the hosted-engine on the first VM (with the engine volume) froom >> the CLI, then log in Ovirt admin, enable gluster support, install *and >> deploy* from the GUI host2 and host3 (where the engine bricks are) and then >> install host4 without deploying.

Am I doing something wrong?
