Podman/docker leave behind old images, image layers, and containers that need to be cleaned up occasionally. podman system prune will do so.
If 8TB was taken up quickly or unexpectedly, it might be something like a container failing to start and being recreated over and over, leaving each failed container behind as it goes. podman ps --all will list all containers, running or stopped. Before doing the system prune run that and podman image ls --all to see if anything looks amiss.
