because i wrote this latter and actually checked here ;)

1 minmute is the grace period where we mark a node as "fencing" required
(see HA::NodeStatus is_node_delayed_offline), but we can only move them
after 2 minutes.

So the will always be moved if the node is away for more than 60 seconds
but only after 2 minutes, where it's lock expires.
