Two new NixOS Proxmox VMs (VMIDs 202/203) forming a dual-manager Docker
Swarm on dedicated vmbr3 (192.168.30.0/24, VLAN 30) for gossip and VXLAN,
with NFS via the storage-client network (vmbr2) from the existing HA cluster.
- nixos/variables.nix: add ha-docker IP/interface/port vars and swarm CIDR
- nixos/modules/build-types/ha-docker.nix: new build type — Docker 29,
NFS mounts, beszel-agent, health monitoring, swarm firewall rules with
checkReversePath = "loose" for VXLAN routing mesh
- nixos/hosts/ha-docker-{1,2}/host.nix: per-host identity — three NICs
(LAN, storage, swarm), IPA dyndns pinned to LAN interface
- nixos/flake.nix: add proxmox-ha-docker-{1,2} targets; build-validated
with nix build --dry-run (169 derivations, no errors)
- nixos/docs/ip-addressing.md: document VLAN 30 / swarm.home zone,
ha-docker IP allocations across all three subnets
- nixos/scripts/docker-swarm/deploy.sh: 10-phase lifecycle script
(bridge, keys, IPA, VMs, swarm init, DNS, verify); modelled on
scripts/ha/deploy.sh with --destroy mode
- nixos/docs/internal/docker-swarm-cutover.md: service-by-service
migration guide covering Traefik log rotation, Nextcloud cron sidecar,
docker-health-to-gotify swarm awareness updates, Passbolt/Gitea steps,
DNS cutover, and CT 105 decommission checklist

- variables.nix: switch to rec {}, extract giteaDomain/giteaRepoPath,
extraAdminSshKeys, haLanNfsFqdn, tailscaleResolverIp, ports.dhcp,
ports.dns; ipaServer now derives from homeDomain ref; section headers
- modules: use new vars throughout (pxe-boot, ts-dns-forwarder,
cluster-config, configuration.nix, mount-pxe-images) — eval unchanged
- docs: delete ephemeral planning docs (AUDIT_REPORT, ha-network-audit,
network-cutover); add docs/ha.md; drop migration reference table from
ip-addressing.md; remove stale server example from beszel.md
- CLAUDE.md/README.md/AGENTS.md: fix build types (tailscale-router,

Removes all flake artifacts for the retired NFS/ZFS file server:
- flake.nix: drop linode-server, proxmox-server, lxc-server targets
- hosts/server/: delete host identity
- modules/build-types/server.nix: delete build type (ZFS pool + NFS exports)
- vars/per-machine/{linode,lxc,proxmox}-server/: delete clan vars
- secrets/server.keytab: delete IPA keytab
- .sops.yaml: remove server key anchors, strip from common.yaml recipients,
delete server.yaml and server.keytab creation rules
- variables.nix: remove serverIp, serverStorageIp (nfsServerHost/storageRoot
retained — pxe-boot/mount-pxe-images.nix still references them)
- docs: mark server decommissioned in ip-addressing.md
Docker NFS mounts already pointed at nfs.storage.home (previous commit).
VM destruction and DNS cleanup (server.sweet.home, server.storage.home
A/PTR records) to follow once the VM is confirmed stopped.

vip-storage (192.168.20.229) now serves NFS as well as iSCSI, firewalled
to haClientCidr (192.168.20.0/24) only. This allows docker and future
swarm nodes to NFS-mount shared volumes from the storage network rather
than the LAN, keeping storage traffic off vmbr0.
LAN NFS (vip-lan 192.168.2.229) remains for pxe-boot and other LAN
clients. Protocol and subnet boundaries enforced by firewall on both nodes.

Renumber internal HA bridges so VLAN ID matches IP third octet:
vmbr1 (cluster): 192.168.4.x → 192.168.10.x (VLAN 10, /29)
vmbr2 (storage): 192.168.5.x → 192.168.20.x (VLAN 20, /24)
Enforce protocol separation at the firewall on both HA nodes:
- iSCSI (3260/tcp): storage-client subnet (192.168.20.0/24) only
- NFS (111,2049,20048 tcp+udp): LAN subnet (192.168.2.0/24) only
- Cluster subnet (192.168.10.224/29) accepted wholesale (DRBD+Corosync)
Moves from allowedTCPPorts/allowedUDPPorts to source-restricted extraCommands
rules on the nixos-fw chain.
NFS exports reduced to LAN-only (drop haClientCidr lines from mkNfsExports).
Storage-client network clients use iSCSI only; no NFS on VLAN 20.
All HA script VIP/storage IP defaults updated to match.

- cluster-config.nix: allow haClientCidr (192.168.5.0/24) in iptables
- ha-server.nix: NFS exports now allow both lanCidr and haClientCidr
- VIP moves from 192.168.2.229 (vmbr0/LAN) to 192.168.5.229 (vmbr2)
- iSCSI portal to be rebound from [::0] to 192.168.5.229 at cutover

nfs-utils changed ConditionPathExists from !/etc/krb5.keytab to
/etc/krb5.keytab, so on IPA-joined hosts the service now starts instead
of skipping. Exports use standard auth (no sec=krb5) so the nfs/ Kerberos
principal is never provisioned and the service fails.
enable = false masks the unit so nfs-server's Wants= can't pull it in.

Deploy/init fixes:
- iscsi-target.nix: targetctl binary is in rtslib-fb (python3 env), not
targetcli-fb — fixes ExecStart and ExecStop for the targetctl.service
- deploy.sh: _patch_targetctl() applies runtime dropin to both nodes before
cluster-init so Pacemaker can manage the iSCSI target from first start
- cluster-init.sh: replace crm configure heredoc with cibadmin --replace XML
(pacemaker-4.0 schema: globally-unique in meta_attributes, promoted-max/
promoted-node-max, Promoted role in constraints); force_unmount=true on
xfs-data; DRBD promote timeout 240s
- cluster-config.nix: add crm-fence-peer.sh/crm-unfence-peer.sh handlers;
update fencing comment to reflect resource-only + Pacemaker-aware handler
replacing STONITH during testing phase
- ha-server.nix: add openiscsi to systemPackages for T4 iscsiadm availability
Acceptance test fixes:
- acceptance-tests.sh: fix ((PASS++)) set -e bug → PASS=$((PASS+1));
detect Active/Standby dynamically via drbdadm role (Pacemaker can promote
either node); T4 bash TCP probe instead of iscsiadm; T5 timeout 120s;

Documentation fixes:
- README/AGENTS: rename tailscale-exit-node → tailscale-router, add ha-server
build type and proxmox-ha-server-{1,2} host table rows, add baremetal to
platform list, remove references to non-existent flake-target-refactor-spec.md
and remove-sensetive-info-refactor.md
- docs/auto-installer.md: fix lxc-tailscale-exit-node → lxc-tailscale-router,
add pxe-minimal to the flake outputs list
- variables.nix: fix domainControllerIp comment — IPA is the authoritative DNS
at .253 (Pi-hole is gone), not a forwarding intermediary
Code deduplication:
- Extract duplicate SSH host-key preservation activation scripts from
modules/platforms/lxc.nix and modules/platforms/proxmox.nix into a shared
modules/common/preserve-ssh-host-key.nix; both platforms now import it
- Replace 8-line hand-enumerated NFS export lists in server.nix and ha-server.nix
with a mkNfsExports helper that generates exports from vars.nfsShares — adding
a share to variables.nix now propagates to both exporters automatically
Dead code removal:
- modules/common/configuration.nix: remove leftover NixOS skeleton comments
(hardware-configuration import, grub lines) that were never used
- modules/docker/enable-service.nix: remove commented-out listenOptions and
daemon.settings blocks
- hosts/server/host.nix, hosts/nix-cache/host.nix: remove #DOCKER_HOST comments

Create an IPA group "docker-access" (GID 50010) and pin the local
"docker" group to that GID on all Docker hosts. Any IPA user in the
docker-access group automatically gains docker socket access through
SSSD supplementary-group resolution — no per-host docker.members
entry needed.
Specific changes:
- variables.nix: add dockerAccessGid = 50010
- modules/docker/enable-service.nix: lib.mkForce docker GID to
dockerAccessGid, removing the need to name individual IPA users
- modules/build-types/docker.nix: remove direct wayne docker.members
entry (access now comes from IPA group)
- modules/ipa/client.nix: refactor repeated security.* / systemd.*
top-level keys into merged attribute sets (fixes statix W20); add
security.pam.services.lightdm.makeHomeDir so the GUI login path
also creates the home dir on first login

zpool create -f was called if `zpool import -d /dev/disk/by-id` failed,
which could happen due to a race with systemd-udev-settle. The disk
would then be visible by the time zpool create ran, silently destroying
all data on an otherwise-intact pool.
Fix: locate the data disk first, retry the import directly against it
as a fallback, then check zdb -l for existing ZFS label metadata before
concluding the disk is blank. Remove -f so zpool create refuses rather
than overwrites if a pool is present.

FreeIPA (the new authoritative DNS) cannot reach 100.100.100.100
(Tailscale's internal MagicDNS resolver) directly because the DC is not
a Tailscale node. The tailscale-router IS a Tailscale node and can
reach 100.100.100.100 via tailscale0, so it now runs a dnsmasq
instance on its LAN interface that forwards all ts.net queries to
Tailscale's resolver.
After deploying this host, configure FreeIPA with:
kinit admin
ipa dnsforwardzone-add ts.net \
--forwarder=192.168.2.222 \
--forward-policy=only
This replaces Pi-hole's conditional forwarder for ts.net and restores
resolution of Tailscale MagicDNS names (e.g. raspberrypi.tail13f623.ts.net)
for all LAN hosts using FreeIPA as their DNS server.

Adds static IP configuration to every NixOS host in the flake that
has a fixed LAN address, and centralises all network primitives
(IPs, gateway, prefix length, interface names) in variables.nix so
there is one place to update if any of them change.
variables.nix additions:
- lanGateway / lanPrefixLength — LAN gateway and /24 prefix, replacing
every hardcoded 192.168.2.254 / 24 across host files
- lxcLanInterface / vmLanInterface / vmStorageInterface — NIC names for
LXC containers (eth0), Proxmox VMs (ens18), and the HA storage NIC
(ens19), used as attribute keys so changing the name is a one-line edit
- haStoragePrefixLength — /29 for the storage subnet, mirrors haStorageCidr
- Per-host IP variables: nixCacheIp (.224), tailscaleRouterIp (.222),
torRelayIp (.221), serverIp (.226), dockerIp (.225)
host.nix changes:
- tailscale-router, tor-relay, nix-cache, pxe-boot: useDHCP = false,
static address on eth0 (lxcLanInterface), struct-form defaultGateway
(required when using systemd-networkd which LXC containers use)
- server, docker: useDHCP = false, static address on ens18 (vmLanInterface),
struct-form defaultGateway (works for both scripted networking and networkd)
- ha-server-1, ha-server-2: replace hardcoded 192.168.2.254 / 24 / 29
with the new variables; no functional change for these hosts
modules/build-types/pxe-boot.nix:
- Domain-controller kickstart template: replace hardcoded 192.168.2.138
and 192.168.2.254 with vars.domainControllerIp / vars.lanGateway /
vars.lanPrefixLength / vars.homeDomain so the template stays correct
if the DC IP or domain is ever changed again

dnsmasq binds port 53 by default even when only proxy DHCP is needed.
systemd-resolved already owns port 53 on the pxe-boot container, so

New modules
modules/ha/cluster-config.nix — DRBD resource + corosync nodelist sourced

modules/build-types/ha-server.nix — imports pacemaker-stack + iscsi-target

mount); nfs-server.service.wantedBy force-cleared so Pacemaker controls
start/stop on the Active node only

hosts/ha-server-{1,2}/host.nix — static IP from vars, unique hostId; sops
secrets (beszel, corosync authkey) are TODOs pending sync-host-keys.sh
variables.nix
haServer1/2Host, haServer1/2Ip, haServerVip, haStorageRoot, haIscsiIqn
ports.haServerDrbd/Iscsi/Corosync{1,2,Crypto}/PacemakerRemoted/Pcsd
scripts/ha/ (migrated + updated from test-lab/ha/)
cluster-init.sh — generates corosync authkey, initialises DRBD/XFS/iSCSI,
creates NFS dataset dirs, configures Pacemaker with DRBD + XFS + iSCSI
+ nfs-server + VIP; STONITH disabled initially (enable separately)
cluster-enable-stonith.sh — enables fence_pve_ssh STONITH after key deploy
fence-pve-ssh.py — Proxmox SSH fence agent (node names updated to ha-server-1/2)
acceptance-tests.sh — T1–T7 production acceptance tests
test-lab/ha/ removed — all Nix config moved to modules/ha/ and

Adds an unattended install option to the PXE boot menu that installs
Rocky Linux 9 and configures FreeIPA on the domain-controller.sweet.home
host without any operator interaction after selecting the menu entry.
How it works:
- fetch-rocky-pxeboot.service downloads the Rocky 9 Anaconda pxeboot
kernel and initrd from the Rocky mirror on first pxe-boot deploy
(idempotent, same pattern as fetch-debian-netboot)
- rocky-freeipa.ipxe boots Anaconda with inst.ks pointing at the
hosted Kickstart and net.ifnames=0 biosdevname=0 for stable eth0
- rocky-freeipa.ks (generated, includes vars.adminSshKey) performs:
- Minimal Rocky 9 install with ipa-server + ipa-server-dns
- Static IP 192.168.2.138 via NM connection file written in %post
- /etc/hosts fixed for FreeIPA FQDN requirement
- Random DM + admin passwords generated and saved to
/root/ipa-credentials.txt (chmod 600, never hardcoded)
- freeipa-first-boot.service oneshot enabled to run
ipa-server-install on the first real boot (~20 min)

showmount and the NFSv3 mount protocol need mountd reachable after querying
portmapper on 111; the server was only opening TCP 111 and 2049, causing
clients (e.g. Proxmox GUI NFS storage scan) to time out connecting to
mountd on 20048. Also adds UDP for all three ports — portmapper, nfsd, and
mountd all use both protocols.

Adds modules/pxe-boot/mount-pxe-images.nix, which mounts
server.sweet.home:/tank/proxmox/pxe-images at /mnt/pxe-images via NFSv4.2
(x-systemd.automount on Proxmox VMs, nofail on LXC containers — same pattern
as docker/mount-data.nix). The pxe-boot build-type now imports this module and
replaces the previous local /srv/pxe/http/images directory rule with an L+
symlink pointing to /mnt/pxe-images, so large images (ISOs, disk images) live
on the NFS share rather than the host's own root disk.

Adds a `fetch-debian-netboot.service` oneshot that downloads the Debian
bookworm netboot kernel and initrd from deb.debian.org on first boot,
stages them under /srv/pxe/http/debian/, and serves them via a generated
debian.ipxe chain script. The service is idempotent — it skips the
download if both files are already present.
Also merges the previously split systemd.tmpfiles.rules and
systemd.services blocks into a single systemd = { ... } attrset to
satisfy statix's repeated-keys lint.

(all three platform variants as recipients). The secrets file must be
created manually before deploying — see instructions in PR.

extraCommands runs after nixos-nat-post is deleted but before it is
re-created, so -A nixos-nat-post silently fails every time. POSTROUTING
is a built-in chain that always exists; target it directly instead.
The -C idempotency check prevents duplicate rules on firewall reloads.
Drop networking.nat.enable -- it was only needed for the sub-chain that
turned out to be the wrong target.

networking.nat.externalInterface without internalInterfaces creates the
nixos-nat-post chain but inserts no MASQUERADE rule into it — confirmed
by inspecting the live firewall-start script on the deployed host.
Add the rule explicitly via firewall.extraCommands targeting nixos-nat-post,
scoped to LAN source traffic (vars.lanCidr) going out tailscale0.
extraStopCommands removes it on firewall stop.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Without SNAT on tailscale0, Tailscale drops forwarded packets from LAN
source IPs (192.168.2.x) because they are not recognised Tailscale
addresses. With networking.nat.externalInterface = "tailscale0", all
traffic leaving through the Tailscale tunnel is masqueraded to the
router's own Tailscale IP (100.x.x.x), making it indistinguishable from
locally-originated traffic. Conntrack handles the return path.

Complete the rename so all identifiers match networking.hostName:
- flake.nix: attribute names and buildType strings
(linode/proxmox/lxc-tailscale-subnet-router → *-tailscale-router)
- modules/build-types/tailscale-subnet-router.nix → tailscale-router.nix
- .sops.yaml: anchor and alias names (age keys unchanged, no re-encrypt needed)
- host-keys/: local gitignored key files renamed (not committed)

The host was always intended as a LAN subnet router (--advertise-routes),
not a full exit node (--advertise-exit-node). Rename every trace of
"exit-node" to "subnet-router" and remove the --advertise-exit-node flag
from extraSetFlags; the operator supplies --advertise-routes at first
tailscale up and Tailscale persists it in state across reboots.
Routing sysctls (useRoutingFeatures = "server"), openFirewall, and
trustedInterfaces = ["tailscale0"] are still required for subnet routing
to work, so the module is kept — just correctly named.
