Hi~Yoshinor

mysql master-slave replication has been successful

This is 5 servers in IDC room,one master and the others is slave

master:10.10.1.109
slave1:10.10.1.110
slave2:10.10.1.193
slave3:10.10.1.194
slave4+mha_manage:10.10.1.195

In the past two days, I run the command: masterha_check_repl - conf = / 
etc/app1.cnf

It's also display OK

But today It's display not ok,But In fact,The master-slave replication is 
Running well

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
This is my /etc/app1.cnf
[server default]
log_level=debug
# mysql user and password
user=root
password=0ps.iz3n3
ssh_user=ops
repl_user=rep
repl_password=bm5123
master_binlog_dir=/var/lib/mysql
# working directory on the manager
manager_workdir=/var/log/masterha/app1
# manager log file
manager_log=/var/log/masterha/app1/app1.log
# working directory on MySQL servers
remote_workdir=/var/log/masterha/app1
[server1]
hostname=10.10.1.109
[server2]
hostname=10.10.1.110
[server3]
hostname=10.10.1.193
[server4]
hostname=10.10.1.194
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Now I run masterha_check_repl --conf=/etc/app1 

display the following

I think maybe it is network problem

Look at this, run masterha_check_ssh --conf=/etc/app1.cnf It's OK

Hi~~~Dear's Yoshinor

Do you think it is a network problem

Network may have problems. Check your network admin. 
The latest MHA (0.55) has a parameter to change ssh connection timeout 
(http://code.google.com/p/mysql-master-ha/wiki/Parameters). Default is 5 
seconds. You may increase timeouts.
