+# This playbook will make custom partition layout for your osd hosts.
+# You should define `devices` variable for every host.
+#
+# For example, in host_vars/hostname1
+#
+# devices:
+# - device_name: sdb
+#   partitions:
+#   - index: 1
+#     size: 10G
+#     type: data
+#   - index: 2
+#     size: 5G
+#     type: journal
+# - device_name: sdc
+#   partitions:
+#   - index: 1
+#     size: 10G
+#     type: data
+#   - index: 2
+#     size: 5G
+#     type: journal
