## How to proceed
For each machine, **one by one** do:
- Check that cluster is healthy
- `sudo gluster peer status`
- `sudo gluster volume status all` (check Online Col, only `Y` must appear)
- Check that Nomad is healthy
- Check that Consul is healthy
- Check that Postgres is healthy
- Run `ansible-playbook -i production --limit <machine> site.yml`
- Reboot
