Need help with second drive testing

[Jhen-Hao Yu]

Hi, everyone,

My name is Howard, an SSD fan who wants to make use of resctl-bench.

I have already used the premade image installed on my root disk to launch resctl-bench, it works fine so far.

The question is when I want to test my second drive (non-root disk), it will show ""Swap backing dev "nvme0n1" is different from scratch backing dev "sda""", and if I try --force to ignore it, the IO info still shows my root disk (/dev/sda).

Any clue about correcting the setting to test on a non-root disk?

I followed the OCP spec 9.8 resctl-bench instructions, but it seems not working.

Thanks for helping.

Best regards,
Howard
