Hi Yanko,

I think the Ceph documentation is not quite accurate.  Not all Intel NVMe S=
SDs have device ID 0x0953.  Similarly, Samsung NVMe SSDs likely have severa=
l different device IDs depending on the model.

I would suggest just doing "lspci | grep Volatile" to find the NVMe SSD bus=
/device/functions on your system.

    Assuming that I gave you enough information. Can anyone spot what I=C2=
