When an error occurs during failover operation, refer to the system log to identify the cause. When cluster applications fail to start, refer to the server.log file to identify the cause.
The server.log file is a file created under the directory specified in the -w option when executing the pgx_pclrsc command. This file has almost the same content as the file specified in the -l option when executing the pg_ctl command to start the database cluster, and errors that are not output to the system log are output to these files, including startup errors.
