[one-users] How to attach ceph volatile disk in opennebula 4.2

[Ruben S. Montero]

Hi

Currently this is not supported. Volatile disks can only be files, as they
are created in the system datastore and it can be only of type shared or
ssh, both file based.

You could (in theory) attach a ceph datablock image, but we've been hit by
a bug in this feature so currently this is broken.

Cheers
