partitions for storing objects.
Ceph Clients retrieve a `Cluster Map`_ from a Ceph Monitor, and write objects to
-pools. The pool's ``size`` or number of replicas, the CRUSH ruleset and the
+pools. The pool's ``size`` or number of replicas, the CRUSH rule and the
number of placement groups determine how Ceph will place the data.
