notify_master is only automatically executed when the switch occurs on one server

[tongalitong]

We have configured two servers with IPs: one is 192.168.2.203 and the other is 192.168.2.229, with a VIP of 192.168.2.111. When 229 switches from backup to master, it can automatically execute the notify_master bound shell script. However, when 203 switches from backup to master, the notify_master bound shell script does not execute. SELinux has been configured to a disabled state.

I have already tried disabling SELinux, but even after 192.168.2.203 switches to master, the notify_master bound enable_write.sh script still does not execute automatically
The enable_write.sh file has 755 permissions.

help!!! help!!!
