Yes, by default BlueStore reports 1Gb per OSD as used by BlueFS.

Taking a look to your computation I think the ratio OSD/Overhead
it's really about 1.1Gb per OSD.
Because I have 9 NVMe OSD alive right now. So about 9.5Gb of
overhead.
So I guess this is just it's right behaviour.
Fine!

[1] Here is a ceph starts on a brand new cluster that has
never had any pools created or data or into it at all. 323GB
used out of 2.3PB. that's 0.01% overhead, but we're using 10TB
disks for this cluster, and the overhead is moreso per osd
than per TB. It is 1.1GB overhead per osd. 34 of the osds are
pure nvme and the other 255 have collocated DBs with their WAL
on flash.
The used space your string is most likely just osd
overhead, but you can double check if there are any orphaned
rados objects using up space with a `rados ls`. Another thing
to note is that deleting a pool in ceph is not instant. It
goes into garbage collection and is taken care of over time.
Most likely you're just looking at osd overhead, though.
