Hi Yanko,
I think the Ceph documentation is not quite accurate. Not all Intel NVMe SSDs have device ID 0x0953. Similarly, Samsung NVMe SSDs likely have several 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.

Hello
My name is Yanko Davila, I´m new to ceph so please pardon my ignorance.
I have a question about Bluestore and SPDK.
I´m currently running ceph version:
ceph version 12.2.10 (177915764b752804194937482a39e95e0ca3de94) luminous
(stable)
on Debian:
Linux <hostname> 4.9.0-8-amd64 #1 SMP Debian 4.9.110-3+deb9u4
(2018-08-21) x86_64 GNU/Linux
Distributor ID: Debian
Description: Debian GNU/Linux 9.5 (stretch)
Release: 9.5
Codename: stretch
I´m trying to add an NVMe osd using bluestore but I´m struggling to find
the device selector for that NVMe. So far I´ve been able to compile
spdk and succesfully run the setup.sh script. I can also succesfully run
the identify example which leads me to think that spdk is working as
expected.
When I read the online manual (
http://docs.ceph.com/docs/master/rados/configuration/bluestore-config-ref/#spdk-usage
) it gives an example for an Intel PCIe SSD:
<quote>
For example, users can find the device selector of an Intel PCIe SSD with:
$ lspci -mm -n -D -d 8086:0953
<quote />
When I try the same command adjusting for my Samsung SSD it returns
nothing or the return is just blank here is what I tried:
$ lspci -mm -n -D -d 144d:a801
Assuming that I gave you enough information. Can anyone spot what I´m
doing wrong? Does spdk only works on Intel SSDs ? Any comment is highly
appreciated. Thank You for your time.
Yanko.
