Hosted engine runs fine on iSCSI since oVirt 3.5. It needs a separate target from VM storage, but then that access is managed by the hosted engine HA system.
Thanks so much, Chris. It sounds like that is exactly what I was missing.
It would be great to know how to add multiple paths to the hosted engine's iSCSI target, but hopefully I can figure that out once I have things up and running.
oVirt doesn't currently support adding paths to an existing storage domain; they all have to be selected when the domain is created. Since the hosted engine setup doesn't support that, there's no way to add additional paths after the fact. I think adding paths to a regular storage domain is something that is being looked at (believe I read that on the list), so maybe if that gets added, support for adding to the hosted engine domain will be added as well. I have a script that gets run out of cron periodically that looks at sessions and configured paths and tries to add them if necessary. I manually created the config for the additional paths with iscsiadm. It works, although I'm not sure that the hosted engine HA is really "happy" with what I did. :) -- Chris Adams <cma@cmadams.net>
