How reproducible:
Install ceph as per below. On the UI, click fileystems dropdown, then click on cephfs. A new page opens, which is frozen.


Steps to Reproduce:
1. Installed on VM's using  https://gitlab.cee.redhat.com/jbrier/jdg-documentation/wikis/RHCS-4-test-cluster-on-VMs#prerequisites
2. Used http://file.rdu.redhat.com/jbrier/rhcs-4-prerelease.repo
3. RPM based install

Actual results:
Working ceph Cluster but CephFS screen freezes up and no MDS performance counters displayed


Expected results:
A working Filesystems, CephFS page

Additional info:
Have installed a few times. My original install using http://file.rdu.redhat.com/jbrier/rhcs-4-20190723.ci.1.repo had a working CephFS page, however there bugs, which have now been resolved.
