I just tried that, it already had a restart done as I fully deleted the old OSD and re-created using the correct hostname after zapping the disk and restarting the server itself.
Just somewhere it still seems to have stored the external IP's of the other hosts for just this OSD, after restarting it's still full of log lines like : no reply from externalip:6801 osd.21, which is a OSD on another node and trying to connect via the external IP of that node.
The 3 other OSD's i created on the same node after the first issue one all are fine and communicating via the internal network correctly, so I know its not a node wide config issue.
Hope that makes sense!

When you stop/start an OSD it will re-register itself with the cluster
and update it's IP.
No need to remove it. Just a stop/start should be sufficient.
