I upgraded ceph to 0.83 (while repairing OSDs I went down to 0.80.5) because it 
was missing that cephfs-journal-tool.  I did a cephfs-journal-tool journal 
inspect and it showed that it was damaged, so did a reset and now I am able to 
mount cephfs again.

Thanks!

Regards,
Hong

I can't really help with MDS.  Hopefully somebody else will chime in here.
