I'm constantly running into NodeUnderDiskPressure in my pods that are running in Minikube. Using minikube ssh to see df -h, I'm using 50% max on all of my mounts. In fact, one is 50% and the other 5 are <10%.

$ df -h

rootfs          7.3G  503M  6.8G   7% /

The probably usually just goes away after 1-5 minutes. Strangely, restarting Minikube doesn't seem to speed up this process. I've tried removing all evicted pods but, again, disk usage doesn't actually look very high.

The docker images I'm using are just under 2GB and I'm trying to spin up just a few of them, so that should still leave me with plenty of headroom.

Here's some kubectl describe output:

Is this a bug? Anything else I can do to debug this?
