So basically you can't have a single OSD available on multiple IP networks because the client will use whatever single address is in the map. So my only options are: 1) As you said, make public1 reachable from public2 via a Layer3 address 2) Set specific OSDs up to be available on public2 for the new clients 3) Don't have two public networks :) _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
