Clustering filesystems are old. RedHat at some point took over the company behind GFS perhaps worth looking into. I've also seen people in edge computing space go for Longhorn instead of Ceph. But I don't know anything about it apart that Ceph is available in Proxmox.
My homelab with Turing Pi 2 is running RPi4 CM and an Nvidia Jetson. Each also have a small SSD (one native, two miniPCI to SATA, and one USB). They could be used with k8s or a clustering filesystem but haven't played with it as of yet.
