I was looking through the latest documentation on ceph.com and I really like some of the new ways of doing things. What I find confusing, however, is the lack of documentation as to what version of ceph you need to be running in order to use the commands. In particular, what is the required version of ceph to run the "ceph osd crush ..." commands?
