Why is iscsi-images showing 37GB, while it should be 30GB? And why 4 > objects instead of 3?
It's not 37GB, it's 37 bytes. Type the following command to output in json format and you will always have values in bytes : ceph df --format json | jq '.' or (in table format): (header="pool bytes_used max_avail"; echo "$header"; echo "$header" | tr '[[:alpha:]_]' '-'; ceph df --format json | jq -r '.pools[]|(.name,.stats.bytes_used,.stats.max_avail)' | paste - - -) | column -t You can see how much space your RBDs take (used over provisioned space) pool by pool.
