Hello I successfully migrated from HE 4.3.10 to HE 4.4.9, but I think I commited a mistake: The HostedEngine vm was running on the host (haboob) where I deployed the upgrade path. Everything was ok except that I deployed it on the wrong host (haboob). So I live migrated the HostedEngine on the centos prexisting host (kilimanjaro) and erase haboob. Then I reinstalled a new host (fuego) to replace haboob. The HostedEngine is able to migrate between kilimajaro and fuego but now the vm seems to not be seen by any host when doing: [root@fuego ~]# hosted-engine --vm-status --== Host fuego (id: 1) status ==-- Host ID : 1 Host timestamp : 3252 Score : 3350 Engine status : {"vm": "down", "health": "bad", "detail": "unknown", "reason": "vm not running on this host"} Hostname : fuego Local maintenance : False stopped : False crc32 : 14527b72 conf_on_shared_storage : True local_conf_timestamp : 3257 Status up-to-date : True Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=3252 (Sun Nov 28 18:27:29 2021) host-id=1 score=3350 vm_conf_refresh_time=3257 (Sun Nov 28 18:27:34 2021) conf_on_shared_storage=True maintenance=False state=EngineDown stopped=False --== Host kilimanjaro.v100.abes.fr (id: 3) status ==-- Host ID : 3 Host timestamp : 65261186 Score : 0 Engine status : {"reason": "vm not running on this host", "health": "bad", "vm": "down_unexpected", "detail": "unknown"} Hostname : kilimanjaro.v100.abes.fr Local maintenance : True stopped : False crc32 : c381cf1e conf_on_shared_storage : True local_conf_timestamp : 65261189 Status up-to-date : True Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=65261186 (Sun Nov 28 19:27:23 2021) host-id=3 score=0 vm_conf_refresh_time=65261189 (Sun Nov 28 19:27:26 2021) conf_on_shared_storage=True maintenance=True state=LocalMaintenance stopped=False When doing hosted-engine --console, it returns: [root@fuego ~]# hosted-engine --console Command VM.getStats with args {'vmID': '74d2966c-2efa-41f0-a5c3-dd383f690a92'} failed: (code=1, message=Virtual machine does not exist: {'vmId': '74d2966c-2efa-41f0-a5c3-dd383f690a92'}) The engine VM is not on this host It is like the vmID was the old 4.3.10 HostedEngine that doesn't exist anymore. How can I make the new HostedEngine vmID be the good one known by HA and hosts? *I'm afraid to lose the HostedEngine vm when stopping it!* Thank you for your precious help. -- Nathanaël Blanchet Supervision réseau SIRE 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet@abes.fr
