Hi all,
we’re running a ceph hammer cluster with 3 mons and 24 osds (3 same nodes) and
need to migrate all servers to a new datacenter and change the IPs of the
nodes.
I found this tutorial:
http://docs.ceph.com/docs/hammer/rados/operations/add-or-rm-mons/#changing-a-monitor-s-ip-address-the-messy-way
<http://docs.ceph.com/docs/hammer/rados/operations/add-or-rm-mons/#changing-a-monitor-s-ip-address-the-messy-way>
regarding the mons (should be easy) but nothing about the osds and which steps
to do if you need to shutdown and migrate the cluster to a new datacenter.
Has anyone some ideas, how to and which steps I need?
Regards,
Marcus
