Description of problem:
Cloned https://bugzilla.redhat.com/show_bug.cgi?id=2029695 to test it for 5.1z1

 - RHCS 5.


Steps to Reproduce:
1. Install RHCS 4 with advanced lvm configuration(Pre-created logical volumes).
2. Upgrade from ceph 4 to ceph5.
3. Run ceph_adoption playbook.
4. After upgradation, follow any of the below:
