Proper way to design filesystems structure for a cluster of diskless nodes

I'm trying to learn the basics of Linux clustering so I started designing a really humble cluster: - **6 worker nodes** (Libre Computer La Frite | Cortex-A53 @ 1.2 GHz | **1GB RAM**) - **1 master node** (Raspberry Pi 4 Model B | Cortex-A72 @ 1.5 GHz | **2GB RAM**) - 16-port Gbit Ethernet switch - 500GB SSD **shared through NFS on the network** I'm planning to only run k3s on it and because of the diskless nature of the workers SBC boards, ***I was wondering which kind of "root filesystem structure**"* i should adopt for the cluster, on the NFS storage. For e.g. : - single-system image with the same shared root fs across all nodes - separate root fs for each node (/opt/node1/\* , /opt/node2/\* , ...) and so on... **Thanks to everyone who will reply!**
