+Using an external journal drive
+-------------------------------
+
+The steps documented above created a journal partition of 5 GByte
+and a data partition with the remaining storage capacity on the same tagged
+drive.
+
+It is a common practice to place the journal of an OSD on a separate
+journal drive. This section documents how to use an external journal drive.
+
+Prepare the storage drive in the same way as documented above:
+
+::
+
+    # <WARNING ALL DATA ON $DISK will be LOST!>
+    # where $DISK is /dev/sdb or something similar
+    parted $DISK -s -- mklabel gpt mkpart KOLLA_CEPH_OSD_BOOTSTRAP_FOO 1 -1
+
+To prepare the journal external drive execute the following command:
+
+::
+
+    # <WARNING ALL DATA ON $DISK will be LOST!>
+    # where $DISK is /dev/sdc or something similar
+    parted $DISK -s -- mklabel gpt mkpart KOLLA_CEPH_OSD_BOOTSTRAP_FOO_J 1 -1
+
+.. note::
+
+   Use different suffixes (``_42``, ``_FOO``, ``_FOO42``, ..) to use different external
+   journal drives for different storage drives. One external journal drive can only
+   be used for one storage drive.
+
+.. note::
+
+   The partition labels ``KOLLA_CEPH_OSD_BOOTSTRAP`` and ``KOLLA_CEPH_OSD_BOOTSTRAP_J``
+   are not working when using external journal drives. It is required to use
+   suffixes (``_42``, ``_FOO``, ``_FOO42``, ..). If you want to setup only one
+   storage drive with one external journal drive it is also necessary to use a suffix.
