Fixed In Version:	ceph-ansible-4.0.43-1.el7cp ceph-ansible-4.0.43-1.el8cp	Doc Type:	Bug Fix
Doc Text:	Cause: in the OSD play of the `switch-from-non-containerized-to-containerized-ceph-daemons` playbook, we disable and stop the systemd unit `ceph.target`. Consequence: It makes the playbook stop any other ceph daemons where we only want to stop OSD services. Fix: With this fix, ceph-ansible doesn't stop `ceph.target`, it only disables it. Result: When collocating other Ceph daemons with OSDs, they all have their corresponding play for managing the transition to container.	Story Points:	---

Description Vasishta 2020-11-26 09:57:59 UTC

Description of problem:
Switch to containerized cluster playbook failed because of some other issue but mds collocated with OSD was stopped by ceph-ansible and not started even though all the OSDs on that node were containerized and were up and running.

Version-Release number of selected component (if applicable):
ceph-ansible-4.0.40-1.el7cp.noarch

How reproducible:
Tried once

Steps to Reproduce:
1. Configure a bare metal cluster with an OSD collocated with MDS
2. Run switch to containerized daemon playbook
3. Induce playbook failure after OSDs are containerized

Actual results:
Services collocated with OSDs are stopped

Expected results:
All services must be up and running if there is no reason to be down.
