ceph-ansible-3.2.8-1
ceph-ansible-3.2.12-1

# ceph --cluster ceph osd find 12

---------------------

Yet shrink-osd.yml still works fine for 3.2.4-1.el7cp and 3.2.0-1.el7cp, because there is no osd_fsid required

https://github.com/ceph/ceph-ansible/issues/3630
Version-Release number of selected component (if applicable):
ceph-ansible-3.2.8-1
ceph-ansible-3.2.12-1
with Ceph cluster version <12.2.11
(tested with 3.2z1 and 3.2z2)

How reproducible:
Always

Steps to Reproduce:
1. Install Ceph cluster version <12.2.11 
2. try to remove osds with shink-osd.yml from these versions:
ceph-ansible-3.2.8-1
ceph-ansible-3.2.12-1
3.

Actual results:
