Why would ephemeral instance disks be copied if the backing store is
a shared system like Ceph.
Sorry for the confusion, I tried to describe the workflow if you use
local disk storage for the instances. Of course there's no disk
copying if you use a storage like ceph.

Hi
where are the ephemeral disks stored?
if you decide to use local storage, your instance's disk would be stored in

Hi,
I have been searching on the internet and could not find an answer to this
question.
I understand that ephemeral disks lives until the VM is destroyed, but where
are the ephemeral disks stored? On local host hosting the VM or in centralized
storage (e.g. Ceph) or can I have both options?
