Feasibility of converting a cloud using local Nova storage to a Ceph RBD backend
Issue
- After initially deploying an overcloud environment with
NovaEnableRbdBackend
set toFalse
, can it be changed toTrue
to enable Ceph storage for Nova ephemeral root disks? - How does changing
NovaEnableRbdBackend
parameter affect the function of the overcloud? - Is it possible to change
NovaEnableRbdBackend
and switch the overcloud's Nova ephemeral storage option to and from Ceph?
