rbd + openstack nova instance snapshots?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

Unfortunately this is expected.
If you take a snapshot you should not expect a clone but a RBD snapshot.

Please see this BP: https://blueprints.launchpad.net/nova/+spec/implement-rbd-snapshots-instead-of-qemu-snapshots

A major part of the code is ready, however we missed nova-specs feature freeze so we haven?t proposed anything for Juno.
So we will push something for Kilo.
