Add fast-cpu and fast-storage labels since this node has a faster CPU
than other cluster nodes and is the NFS host with fast local storage.
Also add k3s-upgrade=disabled to exclude from system-upgrade-controller.
Add reusable k3s-node role with configurable options for server/agent
modes. Configure john-endesktop as a k3s agent joining the cluster at
10.0.0.222.
Role supports:
- Server or agent role selection
- Configurable server address and token file
- Graceful node shutdown
- Optional firewall port opening
- Cluster initialization for first server
Note: NixOS nodes must be labeled with `k3s-upgrade=disabled` to exclude
them from the system-upgrade-controller, since NixOS manages k3s upgrades
through Nix rather than in-place binary replacement.
Create configuration to migrate john-endesktop from Arch Linux to NixOS while
maintaining existing ZFS pools (media JBOD and swarmvols mirror) and NFS
exports for k3s cluster.
Configuration includes:
- ZFS support with automatic pool import
- NFS server exporting both pools to 10.0.0.0/24
- Correct ZFS hostid (007f0101) to resolve hostid warnings
- Btrfs root filesystem on nvme0n1p5 (810GB)
- Comprehensive migration plan with rollback procedures
The migration is designed to be safe with Arch Linux remaining bootable
as a fallback until NixOS is verified stable.
