Hi we have a second controller offline(follower)
I didn't know why please help
Ping is ok By the way
And thank you
Upon reviewing the cluster configuration, we identified the primary issue with SZ104-2 (Follower). Attempts to start the service were unsuccessful, and all services remain down. The logs indicated the following errors:
((```
