Good morning everybody!

I'm trying to raise a scenario with redundancy at the storage level.
I'm using CEPH with RBD-mirror.

Cinder has a pretty clear documentation about it, but I didn't find anything about Glance and the "nova_libvirt_images_rbd_pool" and the "cinder_service_backup_driver".

What would be the best approach?
Only use Cinder with Mirror?
If by chance the "nova_libvirt_images_rbd_pool" dies, if you are using config-drive the disk will die, correct? In this case, would it be better to leave local?

I can't see what would be the best scenario for Failover cases with OSA.

Thanks in advance!
