You can't mount until mds replay completes. Probably it is blocked on osd io? Can uou repeat with 'debug ms = 1' in ceph.conf?

To diagnose this sort of problem we need to see 'ceph -s' (to know if osds are up, etc.). If they are, then the mds log (/var/log/ceph/mds*) with 'debug ms = 1' debug level enabled so we can see what IO requests are blocking during replay.
