Well finally it fails with:
2022-02-04 09:14:55,779Z ERROR
[org.ovirt.engine.core.bll.storage.domain.AddPosixFsStorageDomainCommand]
(default task-2) [25a32edf] Command
'org.ovirt.engine.core.bll.storage.domain.AddPosixFsStorageDomainCommand'
failed: EngineException:
org.ovirt.engine.core.vdsbroker.vdsbroker.VDSErrorException:
VDSGenericException: VDSErrorException: Failed to CreateStorageDomainVDS, error
= Could not initialize cluster lock: (), code = 701 (Failed with error
unexpected and code 16)
I think this feature (local storage) no longer works.
