@wongma7 @jsafrane Update the PR as migration test was failing. Notice that some migration test cases set partition as "0", so explicitly check that scenario and ignore partition 0. Please LMK if you have any idea on this

should we validate it? Check that it's an integer? and not something crazy/malicious with weird paths and whatnot.

Yeah, parse to int makes sense to me, is there any special rule for windows partition validation? should that be same?

You can leave it same, I'll test it out later.

I think I will make the windows findDevicePath implementation ignore the partition arg. From my understanding, the windows mount code will always mount the first partition so it doesn't matter what partition is set to. https://github.com/kubernetes-csi/csi-proxy/blob/d47b9ecde8f020dd9d5eb2df3e56bf2f10a3f4a3/internal/os/volume/api.go#L87 (similarly, fstype gets ignored in windows world)
