Sage,
I have the same issue with ceph 0.61.3 on Ubuntu 13.04.
ceph@ceph-node4:~/mycluster$ df -h

What version of the kernel are you using on the client? There is an
annoying compatibility issue with older glibc that makes representing
large values for statfs(2) (df) difficult. We switched this behavior to
hopefully do things the better/"more right" way for the future, but it's
possible you have an odd version or combination that gives goofy results.
