You can do it on a life cluster. The more cavalier approach would be
to quickly switch the link over one server at a time, which might
cause a short io stall. The more careful approach would be to 'ceph
osd set noup' mark all the osds on a node down, move the link, 'ceph
osd unset noup', and then wait for their peers to mark them back up
before proceeding to the next host.
