Let’s say you need to emergency transfer to master one of your hosts, does each host contain the information to become master or is there something else that needs to be done?

I know with HA that at least 2 hosts keep the master info so that failover can be done rapidly, but I never thought about regular pools.

All non master hosts in a pool have the data so any one of them can be promoted.
