# Decommissioning a host
1. remove the host from `tor-nagios/config/nagios-master.cfg`
2. if applicable, stop the VM: `virsh destroy $host`
3. if applicable, undefine it: `virsh undefine $host`
4. if applicable, remove the LVM logical volumes or virtual disk files
5. remove it from ud-ldap: the host entry and any `@<host>` group memberships there might be as well as any sudo passwords users might have configured for that host
6. if it has any associated records in tor-dns/domains or auto-dns, or upstream's reverse dns thing, remove it from there too
7. on pauli: `read host ; puppet node clean $host.torproject.org && puppet node deactivate $host.torproject.org`
8. grep the `tor-puppet` repo for the host (and maybe its IP addresses) and clean up
9. clean host from `tor-passwords`
