+# Sample ceph ceph.conf file.

+# This file defines cluster membership, the various locations
+# that Ceph stores data, and any other runtime options.
+
+# If a 'host' is defined for a daemon, the init.d start/stop script will
+# verify that it matches the hostname (or else ignore it). If it is
+# not defined, it is assumed that the daemon is intended to start on
+# the current host (e.g., in a setup with a startup.conf on each

+## Metavariables
+# $cluster ; Expands to the Ceph Storage Cluster name. Useful
+# ; when running multiple Ceph Storage Clusters
+# ; on the same hardware.
+# ; Example: /etc/ceph/$cluster.keyring
+# ; (Default: ceph)
+#
+# $type ; Expands to one of mds, osd, or mon, depending on
+# ; the type of the instant daemon.
+# ; Example: /var/lib/ceph/$type
+#
+# $id ; Expands to the daemon identifier. For osd.0, this
+# ; would be 0; for mds.a, it would be a.
+# ; Example: /var/lib/ceph/$type/$cluster-$id
+#
+# $host ; Expands to the host name of the instant daemon.
