+Dependencies:
+ - Executed on the fat storage nodes
+ - Ands data VG and mount-point should be configured or they will default to 'ands' and /mnt/ands
+
+Parameters:
+ - ands_data_path: Mount point of Ands Data Volume, defaults to '/mnt/ands'
+ - ands_data_vg / ands_data_lv / ands_data_device / ands_data_volume_size: Configures the LV for Ands Data Volume, VG defaults to 'ands'
+    - The Katrin VG will be created if not existing. The first non-partitioned device with at least 'ands_data_device_threshold' GB of space 
+    will be used unless device is directlys specified with 'ands_data_device'. If ands_data_vg already exists, the 'ands_data_deivce'
+    will be ignored.
+    - Unless 'ands_data_volume_size' is specified, all available space on VG will be used (after creating heketi volume if it
+    resides on the same VG)
+ - ands_heketi_vg / ands_heketi_lv / ands_heketi_device / ands_heketi_volume_size: Configures the LV for Heketi volume manager
+    - The heketi LV is only created if 'ands_heketi_volume_size' is specified in the inventory
+    - By default, the 'ands_data_vg' will be used to create heketi volumes.
+    - If ands_heketi_device is specified, the VG will be created if not existing.
+
+Facts:
+ - ands_data_path:
+ - ands_data_vg:
+
+Actions:
+ - Configures Ands VG & LV on the storage nodes (and detects appropriate devices unless set in inventory)
+ - Mounts Ands data volume
