Migrate Block Volumes and VMs

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

 



Hi everybody,

My OpenStack System use Ceph as backend for Glance, Cinder, Nova. In the future, we intend build a new Ceph Cluster.
I can re-connect current OpenStack with new Ceph systems.

After that, I have tried export rbd images and import to new Ceph, but VMs and Volumes were clone of Glance rbd images, like this:

rbd children images/e2c852e1-28ce-408d-b2ec-6351db35d55a@snap

vms/8a4465fa-cbae-4559-b519-861eb4eda378_disk
volumes/volume-b5937629-5f44-40c8-9f92-5f88129d3171


How could I export all rbd snapshot and its clones to import in new Ceph Cluster?

Or is there any solution to move all Vms, Volumes, Images from old Ceph cluster to the new ones?

Thanks and regards.
