Hi everyone so there is a question to check since I have not done much with
ceph if you have an option to delete it on the UK what will be the command cli
equivalent be?
Thanks

Oggetto: Re: [Openstack] Root disks with Ceph
John: I'm talking about primary root disk storage. Secondary storage would
persist of course.
Mike: Right, I just want to establish that if I set the default Cinder plugin
to RBD volumes, and I do nothing else, root volumes are ephemeral. That seems
to be the case anyway.
Seems like some of these parameters become meaningless depending on your
backing store. As another example, do you really need to specify a root disk
parameter if you're booting from a volume? I would think not.
Thanks for your responses.

When you create an instance backed by an RBD Cinder volume, you can specify
which behavior you want. There is a check box in Horizon to toggle the behavior.
Thanks,

So if I use RBD as my storage backend for Cinder, what happens to the
root disks of VMs that I terminate?
Do they still exist as RBD volumes in Ceph or are they
deleted/marked-as-free?
If the answer is that they get deleted, or at the very least OpenStack
no longer keeps track of them, then there isn't much difference between
the root and ephemeral disks in the flavors I am using. other than their
being distinct disk devices. Or so it seems to me.
