NVME User Installation

NVME User Installation

[Ian Ziemba]

Hi,

I am currently having trouble installing the nvme-user package on my system. Currently, I have an NVMe device up and running in my system. My current configuration is a Dell R720 running SLES 11 SP3 with a Linux kernel version of 3.0.76. In order to get my NVMe device to run, I had to use the nvme-compatibility driver. I would like to get the temperature reading off of my drive, but with my current setup, I cannot install the nvme-user package. Unfortunately, upgrading kernel versions is not an option.

Any insight into how to install the nvme-user package on my system would be greatly appreciated.

Thanks,

Most likely you don't have the nvme driver's user-api header in your
include path. The compatibility driver has a copy at

  include/uapi/linux/nvme.h

If you know where your kernel headers are installed, you can just copy
it there and should be able compile the user tools after.

Hi Keith,

I copied over /uapi/linux/nvme.h into the correct location. The system does not seem to have any issues finding it. But, I ran into something else right now. Here is the printout from my screen:

I have ran into this before and haven't found a way to get around it...

Thanks,

I just tired a SLES11 SP3 install and copied the nvme user api header
from the nvme-compatibility repo's 'include/uapi/linux/nvme.h' to
'/usr/include/linux/', and was able to build the user tools without error.

I'm not sure what else could be different between our two setups that
is causing the errors you're seeing.

NVME User Installation

[Ian Ziemba]

Keith,

When you installed SLES11 SP3, by chance did you do a full install? I just have a base version installed currently on my system. Wondering if maybe there could be a specific SLES11 SP3 package that needs to be installed.
