Make Openstack work with Ceph

Make Openstack work with Ceph

[Chu Duc Minh]

Hi, i have built a Ceph cluster and a Openstack cluster for dev
Ceph work quite smooth, i can mount it to client, or create disk image 
by using rbd, qemu-img,... command.
But i dont' know how to make openstack use new Ceph cluster as the 
default Block Device Storage.
(Openstack use KVM as default hypervisor and QCOW2 as default disk image 
format)

Can you give me some hint to configure Openstack(libvirt/..) to make it 
work with Ceph, pls?

Thanks very much, folks!

Hi,

Right now there's no clean way to do this. You need few scripts to
achive this. First you need to create volume, prepopulate it with
image from glance and later create an instance booting from it.
Scripts below are doing this task.

https://github.com/ceph/ceph-openstack-tools/blob/master/start-on-rbd.sh
https://github.com/ceph/ceph-openstack-tools/blob/master/boot-from-volume


This is good enough but I'am working on solution to implement volume
imaging directly from nova-compute component. It's should be made
public within 3/4 weeks.

I have some problem with "boot-from-volume" script. Maybe the reason is 
i'm using Keystone and this script is not compatible.
And I have problem with ceph-client-tools package(on Openstack cluster) 
because it's different with version of Ceph that i used to build 
Ceph-cluster.
I wil rebuild next day and report result.

Thanks you for fast response!

Did you change admin:admin and project_id to sth which is appropriate
in your setup ? Script it self is compatible with keystone.

That sounds great! I'd be happy to review it and help get it upstream.

I, also, am watching this closely as I'd like to see it integrated
into OpenStack (and thereby into PentOS).
