I am new to Rancher and Kubernetes so I'll appreciate it if you can help me on this one.

I have a Proxmox VM (Ubuntu server 20.04.2) on which I have installed Docker and Kubernetes and containerized Rancher. I have only this one node. Currently I have dedicated 60GB to the Ubuntu server (which can expand up to 465GB).

My cluster is displayed as Unavailable. The error message is "Node has disk pressure".

I read that this may be caused by a large amount of log files and tried increasing the disk size of the Ubuntu server (it was previously 20GB), but this didn't solve the issue.

I had a similar issue with a pod previously and restarting the Ubuntu server fixed it. I tried restarting Ubuntu, and the whole Proxmox server as well, but nothing solved it this time.

df -i says only 20% of inodes used

I am completely lost as to how to fix this issue and what is causing it.

Thank you in advance!
