Ceph - During running "ansible-playbook site.yml" on deployed cluster fails on TASK "restart ceph osds daemon(s) - non container"

Issue

We were introducing some changes on our RHCS environment running "ansible-playbook site.yml" and it keeps failing on TASK "restart ceph osds daemon(s) - non container" without obvious reason:
