    Hi everyone.

      
      I have 83 osds, and every osds have same
      2TB, (Capacity sumary is 166TB)

      I'm using replicate 3 for pools ('data','metadata').

      
      But when mounting Ceph filesystem from somewhere (using: mount -t
      ceph Monitor_IP:/ /ceph -o name=admin,secret=xxxxxxxxxx")

      then capacity sumary is showed "160TB"?, I used replicate 3
          and I think that it must return
          160TB/3=50TB?

      
      Filesystem                Size  Used Avail Use% Mounted on

      192.168.32.90:/    160T  500G  156T   1%  /tmp/ceph_mount

      
      Please, explain this  help me?
