Description
1. I was running IOs on cephfs and replicted pools and noticed that estimated data is more than actual data.
ceph -s

2. Replication size is 2 on all the pools. There are no clones or snapshots.
3. Ran the same test on just the replicated pools,here notional data was half of used data(as replication was 2)
