Description

ceph version: firefly

The command "ceph df" shows the data usage and i see that rbd pool reported used size is 2.5x more than the actual pool size, this is misleading.

pasting the output of the command below,

GLOBAL:
    SIZE     AVAIL      RAW USED     %RAW USED 
    121T     49701G       74390G         59.95
