# This recipe creates a monitor cluster
#
# You should never change the mon default path or
# the keyring path.
# Don't change the cluster name either
# Default path for mon data: /var/lib/ceph/mon/$cluster-$id/
#   which will be /var/lib/ceph/mon/ceph-`hostname`/
#   This path is used by upstart. If changed, upstart won't
#   start the monitor
# The keyring files are created using the following pattern:
#  /etc/ceph/$cluster.client.$name.keyring
#  e.g. /etc/ceph/ceph.client.admin.keyring
#  The bootstrap-osd and bootstrap-mds keyring are a bit
#  different and are created in
#  /var/lib/ceph/bootstrap-{osd,mds}/ceph.keyring
