[ovirt-users] Ovirt with Hosted Engine and 4 Hosts

[Kasturi Narra]

Hello Gabriel,

           Any specific reason  you are looking to expand storage for
engine volume?

          If you are running a HC setup recommended way of upgrading the
setup is to add three more hosts to the existing cluster and create volumes
out of the bricks carved from those additional hosts .

        We do not recommend adding bricks to existing volumes in the HC
setup as it might lead to some issues.

Hope this helps !!!

Thanks
kasturi
