Rancher Agent install fails on RHEL 7.9

Hello there,

I’m trying to import an existing k3s cluster running on RHEL7.9 and whenever I try to deploy the rancher agent, it continually fails with CrashLoopBackoff messages trying to start the cattle-cluster-agent and complains about filesystems being busy in /var/lib/rancher/k3s/agent/containerd/tmpmounts/contained-mount. I’m trying a few different things and am digging through logs - but has anyone seen this before?
