-It is required to define the `type` for crush buckets and these types must start with `root` (top) and end with `host`. OSD daemons will be assigned to hosts according to it's hostname. Weight of the buckets will be calculated according to weight of it's childen.
+It is required to define the `type` for crush buckets and these types must start with `root` (top) and end with `host`. OSD daemons will be assigned to hosts according to it's hostname. Weight of the buckets will be calculated according to weight of it's children.
+
+If the pools that are in use have size of 3 it is best to have 3 children of a specific type in the root CRUSH tree to replicate objects across (Specified in rule steps by 'type region').

+Generate CRUSH map - Alternative way
+------------------------------------
+
+It's necessary to create per OSD pillar.
+
+.. code-block:: yaml
+
+    ceph:
+      osd:
+        crush:
+          - type: root
+            name: root1
+          - type: region
+            name: eu-1
+          - type: rack
+            name: rack01
+          - type: host
+            name: osd001
+
+
+Apply CRUSH map
+---------------
+
+Before you apply CRUSH map please make sure that settings in generated file in /etc/ceph/crushmap are correct.
+
+.. code-block:: yaml
+
+    ceph:
+      setup:
+        crush:
+          enforce: true
+        pool:
+          images:
+            crush_rule: sata
+            application: rbd
+          volumes:
+            crush_rule: sata
+            application: rbd
+          vms:
+            crush_rule: ssd
+            application: rbd
+
+
+Persist CRUSH map
+--------------------
+
+After the CRUSH map is applied to Ceph it's recommended to persist the same settings even after OSD reboots.
+
+.. code-block:: yaml
+
+    ceph:
+      osd:
+        crush_update: false
+
