>Description:
Hello,

I am trying to create partition and file system, and then mount the device for read/write, on a NVME based SSD. Using FreeBSD 9.2 version. 
Created a loader.config file in /boot. Added
nvme_load="YES"
nvd_load="YES"

lines to the loader.config file. After a reboot I see my device getting listed in /dev. It shows /dev/nvme0 and /dev/nvme0ns1.

After this, basic nvmecontrol commands work fine and provide all the details about the device. 

Next, I used the below commands to create partition and file system. But I get the errors as shown
CODE: SELECT ALL
gpart create -s gpt /dev/nvme0ns1  
Error: Invalid argument

gpart create –s gpt /dev/nvme0
Error: Invalid argument

gpart show /dev/nvme0ns1
Error: No such geom.  

newfs /dev/nvme0ns1
Error: reserved not less than device size 0

I followed the same conventions as used for ATA devices as given in some of the examples in freebsd.org. (/dev/ada0). But it does not work for me. Could you please help me to resolve the above errors and let me know how do I give the NVMe based SSD name for the above commands?

>How-To-Repeat:
Just follow the same steps as specified above, the problem will be seen.
