+  warning has been reduced from 300 to 200 PGs.  200 is still twice
+  the generally recommended target of 100 PGs per OSD.  This limit can
+  be adjusted via the ``mon_max_pg_per_osd`` option on the

+  make the number of PGs per OSD exceed the configured
+  ``mon_max_pg_per_osd`` limit.  The option can be adjusted if it
+  is really necessary to create a pool with more PGs.
