Thanks, John.
That seems will take care of monitors, how about osd? Any idea how to
change IP addresses without triggering a resync?
IPs of OSDs are dynamic. Their IP is no part of the data distribution.
Simply renumber them and restart the daemon.
I suggest:
1. Stop OSD(s)
2. Renumber machine
3. Start OSD(s)
That should be all. There will be some recovery due to I/Os which
occurred between 1 and 3.

Fred,
I'm not sure it will completely answer your question, but I would
definitely have a look at:
http://ceph.com/docs/master/rados/operations/add-or-rm-mons/#changing-a-monitor-s-ip-address
There are some important steps in there for monitors.

We need to move Ceph cluster to different network segment for
interconnectivity between mon and osc, anybody has the procedure
regarding how that can be done? Note that the host name
reference will be changed, so originally the osd host referenced
as cephnode1, in the new segment it will be cephnode1-n.
Thanks,
