-# 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
-# node).
-
-## 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.
-#
-# $name ; Expands to $type.$id.
-# ; Example: /var/run/ceph/$cluster-$name.asok
