Hmmm. It looks like we need to rework the OSDs so they subscribe to
map updates when full. Try running "rados -p data bench 10 write". It
will fail, but let it go for a few seconds and it should cause all the
OSDs to update their maps and begin shuffling data.

either:
ceph mon injectargs --mon_osd_full_ratio 96
or
ceph mon injectargs "mon osd full ratio = 96"
should work.
