Hi, I've recently deployed fresh cluster via ceph-ansible. I've not yet
created pools, but storage is used anyway.

[root@ceph01 ~]# ceph version
ceph version 13.2.1 (5533ecdc0fda920179d7ad84e0aa65a127b20d77) mimic
(stable)
[root@ceph01 ~]# ceph df
GLOBAL:
    SIZE        AVAIL       RAW USED     %RAW USED
    269 TiB     262 TiB      7.1 TiB          2.64
POOLS:
    NAME     ID     USED     %USED     MAX AVAIL     OBJECTS
[root@ceph01 ~]# rados df
POOL_NAME USED OBJECTS CLONES COPIES MISSING_ON_PRIMARY UNFOUND DEGRADED
RD_OPS RD WR_OPS WR

total_objects    0
total_used       7.1 TiB
total_avail      262 TiB
total_space      269 TiB
[root@ceph01 ~]#


Regards
Jakub
