Hi Bryan,
Unless you have been playing with 'osd primary-affinity' command, the
problem is probably that you have chooseleaf_vary_r tunable set in your
crushmap. This is a new tunable, it will be supported in 3.15. If you
disable it with
ceph osd getcrushmap -o /tmp/crush
crushtool -i /tmp/crush --set-chooseleaf_vary_r 0 -o /tmp/crush.new
ceph osd setcrushmap -i /tmp/crush.new
you should be able to mount cephfs on 3.14.
Thanks,
Ilya
