Hi all,
Is there a way to enable the Gluster Service for a cluster in the hosted
engine deploy?
In the config append you make the gluster service available with:
OVESETUP_CONFIG/applicationMode=str:both. But how would one enable it?
I would like to enable it automatically. Now I change it afterwards with
API, but after the change I have to put the hosts into maintenance and
activate them again. It would seems there must be a better way to do this.
Thanks,
Renout

Hi,
Trying to add iSCSI storage domain to oVirt 4.0.2 but failing to attach
the Storage Domain to DC. Added storage domain is constantly locked and
DC is constantly in maintenance. How do I get the Storage Domain
activated and initialise DC?

Is it now in version 4.0.2 (or previous 3.6.x) fully supported? Or still in
testing?
As described here:
http://www.ovirt.org/develop/release-management/features/engine/self-hosted…
Only with Gluster I presume...
Is there any bug tracker to see a list of all potential
problems/limitations or features not supported?
Thanks,
Gianluca
