[ovirt-users] Hosted engine disk migration

[Christophe TREFOIS]

This procedure is what makes so scared.

Restoring a backup, usually, ends up in cataclysmic nightmares. Maybe not so in oVirt :)

Is there a recommended way to test restoring an ovirt-engine backup to see if it would “fail” or “work” in production?

I'm on oVirt 3.6

I'd like to migrate my hosted engine storage to another location and have a few questions:


There is no special procedure to migrate the Hosted Engine storage to a new one.
A possible way to do that is to backup the oVirt Engine data and restore them on a newly deployed Hosted Engine using the new storage location as if it was a migration from bare metal to hosted engine.




(a) what is the right syntax for glusterfs in /etc/ovirt-hosted-engine/hosted-engine.conf? (I'm currently on nfs3)

(b) what is the right syntax for fibre channel?

(c) where are instructions for how to migrate the actual disk files? (google was little help)

(d) Can the hosted engine use the same (gluster/fibre) volume as my VM Images?

(e) I get various "Cannot edit Virtual Machine. This VM is not managed by the engine." in the console for manipulating the HostedEngine.  Is that expected?
