Rick, can you provide the json as attachement so we can inspect it ?

The 'smartctl -a --json /dev/sdb' is working fine, it's just that the invocation via the ceph tell osd.X is returning nothing.
This is what the OSD is doing:
https://github.com/ceph/ceph/blob/master/src/osd/OSD.cc#L6250
so the possible issues I see are
1- sudo. whoever teh ceph-osd process is running as is probably not in sudoers yet
2- smartctl not in path.. on my box it's /usr/sbin, perhaps we should specify that explicitly?
3- the smart otput is failing to parse as json here
https://github.com/ceph/ceph/blob/master/src/osd/OSD.cc#L6234
My money is on 1 or 2.
