Cant find out why this can happen:
Got an HEALTH_OK cluster. ceph version 0.87, all nodes are Debian Wheezy
with a stable kernel 3.2.65-1+deb7u1. ceph df shows me this:
*$ ceph df*
GLOBAL:
SIZE AVAIL RAW USED %RAW USED
*242T 221T 8519G 3.43 *
POOLS:
NAME ID USED %USED MAX AVAIL OBJECTS
rbd 2 1948G 0.79 74902G 498856
ec_backup-storage 4 0 0 146T 0
cache 5 0 0 184G 0
block-devices 6 827G 0.33 74902G 211744
Explanation:
Total space = Used space + Available space:
*242T <***8,5T + *****221T***, but MUST be equal is not it? Where I have
lost aproxymately 12,5 Tb of space?
*
**$ ceph -s*
cluster 0745bec9-a7a7-4ee1-be5d-bb12db3cdd8f
