What that procedure describes is backing up an existing engine,
installing a new one and then restoring the backed up data into it.
This was probably written to describe migration from a stand-alone
engine host, not an AllInOne.
Theoretically this should work for your setup, but I am not sure if
the new hosted engine will be able to properly use the AllInOne node
as a hypervisor (it would probably depend on the copied configuration
containing enough details to allow the engine to connect to it over
the network. you will probably at the very last have to shut down the
existing engine before starting up the hosted engine)
I would suggest doing as many backups as you can before starting, and
performing the H.E. setup on a host that wasn't used by the existing
engine, that way if it fails you can just shut it down and bring your
old engine back up.

I got a backup running at this moment, scping /gluster/ovirt/d44ee4b0-8d36-467a-9610-c682a618b698/images/ to a third device.

So, once done, i'll give a shot on the node2 which is running only VDSM as Host agent.

Hope all will be fine !

Hi,

My backups are done, i'm now processing the installation for having the engine in a VM but i got the following error at the first step:

 

 

 

Ok i put the node2 in maintenance and it continues but i got a new error:

I don't understand what is it expecting for the PATH ? i've no idea what  INSTALLATION MEDIA is about.

 

Could you please give me a clue ?

Thanks

Nico
