ceph cluster shrinkage(remove Node,Mons,Osds)

This seems like:
HTTP POST on /api/mon/delete
HTTP POST on /api/osd/delete

possible use cases:
* delete just one OSD from a node
* stop all ceph processes on a node, delete OSD data, remove packages
* stop a monitor and delete it's config

I think we need to discuss the exact use-cases here since the requirement is not clear
Comment 4 Christina Meno 2016-02-11 22:44:57 UTC 
I met with Dusmant and we agreed
If we provide this functionality USM will be responsible for validating/dealing with the result in the cases where we would be asked to perform an operation that damages the clusters ability to store data
Comment 5 Christina Meno 2016-03-01 17:29:01 UTC 
Andrew does ceph-ansible have this capability
Comment 6 Andrew Schoen 2016-03-21 17:18:24 UTC 
ceph-ansible does not currently have the ability.
Comment 9 Jeff Applewhite 2016-10-14 13:13:49 UTC 
what is the status of this in ansible presently - still not addressed?
