Re: ceph df : negative numbers

I've not been able to reproduce an issue with exactly same version of
your cluster.

./ceph -v
ceph version 10.2.5 (c461ee19ecbc0c5c330aca20f7392c9a00730367)

./rados df | grep cephfs
cephfs_data_a         409600          100            0            0
        0            0            0          100       409600

./rados -p cephfs_data_a ls | wc -l
100

If you could reproduce an issue and let us share procedure, that would
be definitely help.

Will try again.

Can you do just `df -h` on your box mounting cephfs or `ceph -s` on
your one of the MON hosts?
