[Ocfs2-users] What is the overhead/disk loss of formatting an ocfs2 filesystem? (Again)

Hi
I found OCFS2 comes with a higher overhead than local fs.
A 5G disk formatted OCFS2 left 3.92G available. And a 161G one left 156G
available.
I found a same question four years ago:
https://oss.oracle.com/pipermail/ocfs2-users/2013-April/006015.html
But the answer is not a precise calculation.
Or without a calculation, which arguments of mkfs.ocfs2 affects the
overhead?
Filesystems formatted via:
'mkfs' '-t' 'ocfs2' '-b' '4K' '-C' '1M' '-N' '16' '-F'
"--fs-features=noappend-dio" DLKDEV
Thanks,
-robin
