The version comparison check should also take the running version into account (daemons might not have been restarted after rpm upgrade). The asok could be used to gather the version of the running daemons:
# ceph --admin-daemon /var/run/ceph/ceph-osd.0.asok version
{"version":"10.2.7-27.el7cp"}
# ceph --admin-daemon /var/run/ceph/ceph-mon.rdh-cu-8.asok version
{"version":"10.2.7-27.el7cp"}
# ceph --admin-daemon /var/run/ceph/ceph-client.rgw.rdh-cu-8.asok version
{"version":"10.2.7-27.el7cp"}
