HI,

we have many groups master slave , used semi-sync are normal.

but there a group master and slave , semi-sync status show have a little question.

slave1 : 10.1.0.62 (MariaDB 10.1.22)

slave2: 10.1.0.63 (MariaDB 10.1.22)

three machine's semi-sync parameter:

rpl_semi_sync_master_enabled ON

rpl_semi_sync_master_timeout 10000

rpl_semi_sync_master_wait_point AFTER_COMMIT

rpl_semi_sync_slave_enabled ON

on master: SHOW GLOBAL STATUS LIKE '%semi%' ;

Rpl_semi_sync_master_clients 1 # should show : 2

......

on slave1: stop slave io_thread;

then on master:　SHOW GLOBAL STATUS LIKE '%semi%' ;

Rpl_semi_sync_master_clients ０

on slave1: start slave io_thread;

on master: SHOW GLOBAL STATUS LIKE '%semi%' ;

Rpl_semi_sync_master_clients 1

on slave2: stop slave io_thread;

then on master:　SHOW GLOBAL STATUS LIKE '%semi%' ;

Rpl_semi_sync_master_clients ０

on slave2: start slave io_thread;

on master: SHOW GLOBAL STATUS LIKE '%semi%' ;
