We want to try the new OpenNebula feature to migrate some images from one datastore to another.
In our case we are using Ceph as storage backend and that makes us wonder if it would be possible to include several Ceph datastores in your OpenNebula configuration. Not just a new Ceph pool within the same Ceph server, I mean a new Ceph storage configured in a different endpoint with different
Right now we are playing around with several OpenNebula cloud clusters and Ceph endpoints and it would be great if it would be possible to migrate some resources like images between them. I think that OpenNebula uses
rbd command to manage the images but (correct me if I’m wrong) it always uses
/etc/ceph/ceph.conf file by default. So to support this the command should be changed by:
$ rbd ls -c /etc/ceph/ceph_ds2.conf -p one --id libvirt
and probably you should include, in your second Ceph DS configuration, a new variable for example:
that should be used by rbd commands if its defined…
The first question, is anyone else interested in this feature?
and the second question for OpenNebula developers , are you willing to include this feature? or do you have some plans already to include something like this?
Cheers and thanks!
