1. Storage.

'ceph df' gives

GLOBAL:
   SIZE     AVAIL     RAW USED     %RAW USED 
   163T      163T         203G          0.12 
POOLS:

   images                    7       2032M         0        55792G         268 
   volumes                   9      65826M      0.12        55792G       16792

'df -h' yields

Ten of the following osds in each of the three storage devices roughly corresponding to MAX AVAIL above.
