Top2: FSC related to Redis: (Redis = https://www.cnblogs.com/ngtest/p/10693750.html)
FSC status really relies on redis service.
For standalone redis system, it’s easy to make sure FSC becomes disconnected (checking status) when the redis is out of service.
But for cluster redis, there are some situations need to consider.
Y---- redis has service, N----redis hasn't service Con----- FSC connected, Dis----- FSC disconnected (checking status). Please note, HA FSC are same as standalone FSC

Please note, these just explain FSC status relies on redis, FSC status also relies on RMQ, TE.
Also, please note, not like replica DBs, cluster redis will change, and keep status after master, slave switching.
