I wouldn't create a separate partition for the DB and let the OSD handle it.
First, you don't waste space (even a couple of GB begin to pile up on a lot
of OSDs) and you have a lot less to manage.
Just create the OSD on the raw device (I use `ceph-volume lvm create
--bluestore --data /dev/sdXY`)

Thanks a lof, Boris.
Do you mean that, the best practice would be to create a DB partition on the
SSD as OSD, and disable WAL by setting bluestore_prefer_deferred_size= 0, and
bluestore_prefer_deferred_size_ssd=0
Or there is no need to create a DB partition on the SSD and let the OSD manages

Hi Samuel,
IIRC at least the DB (I am not sure if flash drives use the 1GB WAL) is
always located on the same device as the OSD, when it is not configured
somewhere else. On SSDs/NVMEs people tend to not separate the DB/WAL on
other devices.
Cheers
Boris
