At least for the mgr, you can just fail-over until it lands on the one you
want it to be running on.

With respect to the MDS, if your reason for asking is because you want
to have the better provisioned MDS as the active then I discourage you
from architecting your system that way. The standby should be equally
provisioned as recovery generally is a resource intense process that
will usually consume more resources than the steady-state active. If
you underprovision memory, especially, then your standup will simply
not function (go OOM).
