Backup Postgres

State is in the database. Nodes do not have a special lease file you must copy.

Backup

Back up Postgres with your usual tool (pg_dump, snapshots, WAL). Include /etc/lattice/entitlement.json and the API config. DHCP nodes are replaceable.

Add a node

  1. Install lattice-dhcpd on the new host.
  2. Point it at the same database and entitlement.
  3. Join it to the VIP (keepalived, L4, or equivalent).

Pools do not move. Relays do not change.
