+<code>
+if you don't have a separate (shared) journal device, you can just down and out the OSD and physically move it from one host to another. (hot-)plugging it in should automatically start the OSD service on the new host, and you can mark the osd as "in" on the GUI.
+if you have a separate journal device only used for the particular osd, you can move it together with the OSD and it should work as well.
+if you have a shared journal device, you might be able to move all the OSDs using it and the journal, all at the same time - I have never tried this though.
+if you only want to move one of several OSDs sharing a journal, this is AFAIK not possible, and you need to actually remove it and create a new OSD from scratch on the new host, using the moved disk.
