Re: Bug? ceph-volume zap not working

If it creates it, should also remove it. Ceph-disk prepare did not 
create it, so it is logical if it does not remove it. ceph-volume 
however creates it, thus should remove it.

Ceph-disk didn't remove an osd from the cluster either. That has never 
been a thing for ceph-disk or ceph-volume. There are other commands for 
that.

	The command mapping from ceph-disk to ceph-volume is certainly not 
1:1. 
	What we are ended up using is:
	ceph-volume lvm zap /dev/sda --destroy
	This takes care of destroying Pvs and Lvs (as the documentation 
says).
