+    The format to use for the CephPools parameter needs to be updated into the
+    form expected by ceph-ansible. For example, for a new pool named `mypool`
+    it should change from:
+    { "mypool": { "size": 3, "pg_num": 128, "pgp_num": 128 } }
+    into:
+    [ { "name": "mypool", "pg_num": 128, "rule_name": "" } ]
+    The first is a map where each key is a pool name and its value the pool
+    properties, the second is a list where each item describes all properties
+    of a pool, including its name.

+    With the migration from puppet-ceph to ceph-ansible for the deployment
+    of Ceph, the format of CephPools parameter changes because the two tools
+    use a different format to represent the list of additional pools to create.
