Hi Jim =


Thank you for your answer. I was able to find the device selector. Now I ha=
ve an issue understanding the steps to activate the osd. Once I setup spdk =
the device disappears from lsblk as expected. So the ceph manual is not ver=
y helpful after spdk is enabled. Is there any manual that walks you through=
 the steps to add an spdk nvme to ceph ?? Thanks again for your time. =


Yanko.
