Hi, > One by directly using rem_lockspace (since it's the hosted-engine one)
The hosted engine lockspace protects the ID of the node. Global maintenance only disables the state machine, but it still reports data to the shared storage. The hosted engine lock can only be released when the agent is down. If the lock is still there even after you call service ovirt-ha-agent stop, then it is a bug somewhere. > the other one by stopMonitoringDomain Shouldn't this be done by VDSM or sanlock when the VM disappears? The lock has to stay acquired any time the VM is running (independently on the hosted engine services or vdsm) to protect the VM's data. We can't release a lock for running VM, because some other host might try to start it and corrupt data by doing it.
