In the MCP 2019.2.6 maintenance update, Mirantis enhanced the Ceph Salt formula
to automatically update the Ceph keyring permissions based on the configuration
of the cluster model. To update the keyrings, apply
salt -C "I@ceph:common" state.apply ceph.setup.keyring from the Salt Master
node.
To obtain the enhancements, follow the steps described in Apply maintenance updates.
