[ceph-users] Move Instance between Different Ceph and Openstack Installation

[Danni Setiawan]

Hi all,

I need to move instance from one Openstack with Ceph to another
different Openstack with Ceph installation. The instance use volume to
boot with another volume attach for data. The instance has 200GB volume
boot and attach with 1TB volume for data.

From what I know, I need to download the volume boot to raw from rbd
then transfer to the new Openstack installation, then reupload to Glance
and create new instance from that image. The problem is uploading to
Glance is quite time consuming because the size of image.

Anyone know the another efficient way to moving instance between
different Openstack with Ceph installation?

Thanks,
Danni

1. Export from "one Openstack with Ceph" image (qemu-img/rbd export).

2. Create in "different Openstack with Ceph" image with same size.

3. Get uuid of this image.

4. Import your data to this image (qemu-img/rbd import).
