Rorthais， Thank you very much for your help. I do according to your comments and the cluster status is ok now.
I want to ask two more questions: 1. This line code in PAF prevent the score to be set. Why does PAF request the prev_state must be shutdown? Could I just set the score if it is not set? if ( $prev_state eq "shut down" and not _master_score_exists() ) 2. The log shows " Transition aborted by operation pgsqld_monitor_0 'create' on node2-1: Event failed ". How could we see the score is not set according this log?
