Hi Cephers,

Documentation on
http://docs.ceph.com/docs/master/rados/operations/erasure-code/ states:

> Choosing the right profile is important because it cannot be modified
> after the pool is created: a new pool with a different profile needs
> to be created and all objects from the previous pool moved to the new.

Right, that makes sense. However, is it possible to "migrate"
crush-failure-domain from osd to host, to rack and so on without copying
pools?

Regards,
Kees
