[ceph-users] cephfs-top: "cluster ceph does not exist"

Hi, just installed pacific on our test-cluster. This really is a minimal, but fully functional cluster. Everything works as expected, except for the new (and by me anticipated) cephfs-top. When I run that tool, it says: "cluster ceph does not exist" If I point it to the correct config file: # cephfs-top --conffile /etc/ceph/ceph.conf I still get the same error. Doesn't matter if I run this as the ceph user or as root. I added the "client.fstop"-user as required by the documentation. module "stats" is enabled and functioning (tested with "ceph fs perf stats"). Anyone any suggestions what might be wrong?
