Basic overview

  • Entrypoint to network is a Linksys WRT1200AC
  • Main HP DL380 G6 server
  • File server is a Custom Intel SC5000 BASE


Self assigned WAN IP address, easily probed via our true domain

Running latest Openwrt trunk, updated every handful of weeks

Performance can be overviewed at:

Main Server

Its hostname is just fosc

Runs NixOS with some nice configs and acts as a docker server. As usual for NixOS, it is configured from .nix files in /etc/nixos

These configs are not intended to be touched by mortals, but can be seen by members so they can help in home server setups

An extensive docker-compose setup is present at /var/docker/ Go there if you have been given access to deploy a stack

RAID setup

NixOS boots from an independent f2fs 250GB SSD.

Real storage is available in a ZFS "RAID10" composed of the 4 mechanical disks. Due to RAID card annoyances, replacing a disk requires a reboot (and probably more intervention)

File Server

This server is currently out of comision. Backups have been taken to offline disks. {.is-danger}

As you would have expected, gordo

Also runs NixOS, using a simpler configuration than the main server.

Its primary function is running an NFS server and beinbg a torrent seedbox. It also has a dormant traefik+docker setup, ready to replace the main server in case of emergency.

RAID setup

Three 1TB SATA disks in raidz (RAID5). The first disk seen by the BIOS contains the GRUB bootloader and a small boot partition aside from one of the three ZFS partitions

Only one disk can fail at the same time. Be careful out there
