[SPDK] FIO Plugin ERROR - Failed to find namespace 'ns=X'

[SPDK] FIO Plugin ERROR - Failed to find namespace 'ns=X'

[OConnell, Brendan]

[-- Attachment #1: Type: text/plain, Size: 283 bytes --]

Hi,
When trying to run the FIO Plugin I get an error:
Failed to find namespace 'ns=X'
I believe I have installed everything correctly and SPDK grabs the drives as expected.

Any ideas where I may have gone wrong?

It's a new Centos7 build with kernel 4.11

Thanks
Brendan

Hi Brendan,

We changed the format expected for 'filename' in the fio configuration file a
few months back so we can support NVMe-oF. You are using the old format, but you
must have pulled updated code. See:

https://github.com/spdk/spdk/tree/master/examples/nvme/fio_plugin

In your config file, change

filename=0000.04.00.0/1

to

filename='trtype=PCIe traddr=0000.04.00.0 ns=1'

That should fix it up.

Thanks,
Ben

I was mistaken and you actually can't use quotes here. It has to be:

filename=trtype=PCIe traddr=0000.04.00.0 ns=1

Sorry about that.
