Hi, I have an existing gluster cluster, it's in production and fully functional. I'd like to be able to manage it from within Ovirt. Can anyone tell me if I can import this gluster setup as it is? I don't want Ovirt to change anything on those hosts.

Thanks, Lucian

Hello Sahina, I've added my existing gluster hosts as well as the VM running the ovirt-engine. It installed vdsm on this VM, set up a bridge called ovirtmgmt and rebooted it. Can you assure me this will not happen with the hosts I have in production. For the moment I cut access for ovirt to the gluster hosts.. my heart just froze when I saw that reboot. :)

This is true for Ovirt version 3.3. Which version are you using?

Yes, since in 3.2 the hosts reboot even for gluster clusters. You might want to consider waiting till the 3.3 GA build is out.(next week)
