[ovirt-users] Hosted Engine VM not imported

[Alessandro De Salvo]

Hi,

I have just migrated my dev cluster to the latest master, reinstalling 
the engine VM and reimporting from a previous backup. I'm trying with 
4.3.0-0.0.master.20180222192611.git01e6ace.el7.centos

I had a few problems:

- the documentation seems to be outdated, and I just find by searching 
the archives that it's needed to add the two (undocumented) options 
--he-remove-storage-vm --he-remove-hosts

- despite the fact I selected "No" to running the engine-setup command 
in the VM (the ovirt appliance), the engine-setup is executed when 
running hosted-engine --deploy, and as a result the procedure does not 
stop allowing to reload the db backup. The only way I found was to put 
the hosted-engine in global maintenance mode, stop the ovirt-engine, do 
an engine-cleanup and reload the db, then it's possible to add the first 
host in the GUI, but must be done manually

- after it's all done, I can see the hosted_storage is imported, but the 
HostedEngine is not imported, and in the Events I see messages like this:

VDSM atlas-svc-18 command GetVolumeInfoVDS failed: Image path does not 
exist or cannot be accessed/created: 
(u'/rhev/data-center/mnt/glusterSD/atlas-fsserv-07.roma1.infn.it:_atlas-engine-02/f02d7d5d-1459-48b8-bf27-4225cdfdce23/images/c815ec3f-6e31-4b08-81be-e515e803edce',)

    the path here is clearly wrong, it should be 
/rhev/data-center/mnt/glusterSD/atlas-fsserv-07.roma1.infn.it:_atlas-engine-02/f02d7d5d-1459-48b8-bf27-4225cdfdce23/images/b7bc6468-438c-47e7-b7a4-7ed06b786da0/c815ec3f-6e31-4b08-81be-e515e803edce, 
and I see the hosted_engine.conf in the shared storage has it correctly 
set as vm_disk_id=b7bc6468-438c-47e7-b7a4-7ed06b786da0.


Any hint on what is not allowing the HostedEngine to be imported? I 
didn't find a way to add other hosted engine nodes if the HE VM is not 
imported in the cluster, like we were used in the past with the CLI 
using hosted-engine --deploy on multiple hosts.

Thanks for any help,
