Hey, this looks like a different report we saw recently off-list!  In that 
case, they were upgrading from 0.80.4 to 0.80.7.  Opening #10105.

You only restarting a single OSD?  I would hold off on restarting any more 
for the time being.

Can you attach the output from

	ls /var/lib/ceph/osd/ceph-NNN/current
and
	ceph-kvstore-tool /var/lib/ceph/osd/ceph-NNN/current/omap list

(you may need to install the ceph-tests rpm to get ceph-kvstore-tool).

Thanks!
