Dead slave during the switch #43

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1.Stop original  master 
2. while the mha monitor is electing slave A to master power down the slave A  
3.check the log 
-------------------
What is the expected output? What do you see instead?
Not sure if this behaviour  is by design, but i would expect that the manger 
when it detects that the slave is not reachable via ssh would try another slave 
( my test environment is 1 master and 3 slaves ) 

What version of the product are you using? On what operating system?
Linux ubuntu 12.04 - mha-5.3 

Please provide any additional information below.
Please see the log below At this line "Fri Dec  7 17:05:33 2012 - [warning] 
HealthCheck: SSH to ip-10-0-1-248 is NOT reachable." manger know that the 
elected master is not reachable and fail the switch. ( make sense to make a 
second check ? ) 

Thanks

----- Failover Report -----

app1: MySQL Master failover ip-10-0-1-149

Master ip-10-0-1-149 is down!

Check MHA Manager logs at ip-10-0-1-45:/var/log/masterha/app1.log for details.

Started automated(non-interactive) failover.
Invalidated master IP address on ip-10-0-1-149.
The latest slave ip-10-0-1-248(10.0.1.248:3306) has all relay logs for recovery.
Got Error so couldn't continue failover from here.

This is an expected behavior. MHA checks all configured instances' status in 
3.1 and if an elected new master is down after that MHA does not retry to 
promote other slave anymore. MHA master promotion is an automated process so 
your test situation is very rare case, and retrying to promote other slave does 
not solve the problem entirely (what if the newly elected slave is down after 
elected?). So stopping failover with error is fine I guess.
