Igor,
Thank you for pointing this section out to me. The information there is
useful, but I would comment for John Dover's interest that the section
was hard to find. I'd been on that page several times before, but
became overwhelmed by the time I got that far down. Maybe the 'What do
I have' section should be at the top and the 'What can I do with it'
section should come second? (My personal opinion, of course).
It is certainly a challenge with a software project this vast to figure
out how to organize the documentation so that it's easy for the
unfamiliar to find what they need.

Hello,
Sorry if this has been asked before...
A few months ago I deployed a small Nautilus cluster using
ceph-ansible. The OSD nodes have multiple spinning drives and a PCI
NVMe. Now that the cluster has been stable for a while it's time to
start optimizing performance.
While I can tell that there is a part of the NVMe associated with
each OSD, I'm trying to verify which BlueStore components are using
the NVMe - WAL, DB, Cache - and whether the configuration generated
by ceph-ansible (and my settings in osds.yml) is optimal for my
hardware.
I've searched around a bit and, while I have found documentation on
how to configure, reconfigure, and repair a BlueStore OSD, I haven't
found anything on how to query the current configuration.
Could anybody point me to a command or link to documentation on this?
Thanks.
-Dave
