Yes, these parts of the profile are just used to create a crush rule. You can change the crush rule like any other crush rule. Paul -- Paul Emmerich Looking for help with your Ceph cluster?

[ceph-users] Altering crush-failure-domain
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?
