rolling_update.yml

---
# This playbook does a rolling update for all the Ceph services
#
# The value of 'serial:' adjusts the number of servers to be updated simultaneously.
# We recommend a value of 1, which means hosts of a group (e.g: monitor) will be
# upgraded one by one. It is really crucial for the update process to happen
# in a serialized fashion. DO NOT CHANGE THIS VALUE.
#
#
# If you run a Ceph community version, you have to change the variable: ceph_stable_release to the new release
#
# If you run Red Hat Ceph Storage and are doing a **major** update (e.g: from 2 to 3), you have two options:
#   - if you use a CDN, you have to change the ceph_rhcs_version to a newer one
#   - if you use an ISO, you have to change the ceph_rhcs_iso_path to the directory containing the new Ceph version
#
