Description

Hi,

ceph version 0.80.1 (a38fe1169b6d2ac98b427334c12d7cf81f809b74)

When creation a cache tiering scheme, some parameters set on the cache tool can not be displayed.

typo in http://ceph.com/docs/master/dev/cache-pool cache sizing section objets rather than objects

As opposed to the display of these parameters that can be correctly displayed.

ceph@firefly1:~$ ceph osd pool get hotpool hit_set_type
hit_set_type: bloom
ceph@firefly1:~$ ceph osd pool get hotpool hit_set_count
hit_set_count: 1
ceph@firefly1:~$ ceph osd pool get hotpool hit_set_period
hit_set_period: 3600
ceph@firefly1:~$ exit
