DOCUMENTATION TAG
(Sorry, Dave, I don't have an answer. I just have the power to fix the
documentation when there is an answer.)

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
