Doc Text:	Before this update, during Red Hat Ceph Storage (RHCS) deployment, Red Hat OpenStack Platform (RHOSP) director generated the CephClusterFSID by passing the desired FSID to ceph-ansible and used the Python uuid1() function. With this update, director uses the Python uuid4() function, which generates UUIDs more randomly.	Story Points:	---

Description John Fulton 2019-12-17 21:35:52 UTC

The CephClusterFSID generated when TripleO deploys Ceph (by passing the desired FSID to ceph-ansible) uses Python's uuid1() [1]. It could be more random however and be generated by Python's uuid4().
