Consider this output:

 The cluster is ~50% full but pool foo only uses ~23% of its max capacity. All pools have 3 replicas. 
 To reproduce: 
 <pre><code class="text"> 
 ../src/vstart.sh -n -s -d 
 bin/ceph osd pool create foo 8 8 
 bin/rados bench -p foo 60 write --max-object-size 4K --no-cleanup 
 bin/ceph df d 
 </code></pre>
