Hi Yanko,

I'm not sure if such a manual exists - one of the Ceph mailing lists may be a better forum to get pointers for that.

    Hi Jim 
    
    Thank you for your answer. I was able to find the device selector. Now I have 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 very 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.
