If I recall correctly, I think ephemeral storage space available is space available under either the K3S install directory (defaults to /var/lib/rancher/k3s IIRC) or system temp (such as /tmp or maybe /var/tmp).

There's a discussion a day or two above that might help you as they were pointing out a specific bug & documentation regarding ephemeral storage.
