Yes, I know this option isn't safe, however, in my current situation, I can't
increase it.
I probably have some files under 4K, however, when I cleaned zero files I didn't saw
any changes in statistics. My current `ceph df details` below:
# ceph df detail

As you can see, the field STORED is 1.6TB. However, the DATA is 6.3.
Does it possible to determine why the files consume so many spaces? Is I am wrong, when I
calculate that size=2 means STORED*2, hence the DATA should be 3.2TB?
