+ Kolla Ceph supports mixed Ceph OSD deployment, i.e. some Ceph OSDs are
+ bluestore, the others are filestore. The ``ceph_osd_store_type`` of each
+ Ceph OSD can be configured under ``[storage]`` in the multinode inventory
+ file. The Ceph OSD store type is unique in one storage node. For example:

+ storage_node2_hostname ceph_osd_store_type=bluestore
+ storage_node3_hostname ceph_osd_store_type=filestore
