Hello, we have setup Rancher 2.8.1 in a 3 VMs (running Ubuntu 20.04) cluster, where: node1 has the Rancher running as a Docker container, node2 is the master node and node3 is the worker node. We see that the VM image size shot up to 74 GB and 82 GB for node1 and node2 respectively (see the screenshot below for node1) In node2, the Rancher UI shows 34 pods and

df -kh

shows 34 overlayfs filesystems, each using 16 GB E.g.

overlay         124G   16G  101G  14% /run/k3s/containerd/io.containerd.runtime.v2.task/k8s.io/e4d7...ddddf/rootfs

My questions: 1. Is this normal for Rancher to use this much of file system ? 2. Is there a way to control the filesystem usage ?
