* @file slave_failover.cpp Check how Maxscale works in case of one slave failure, only one slave is
|
|
* configured
|
|
*
|
|
* - Connect to RWSplit
|
|
* - find which backend slave is used for connection
|
|
* - blocm mariadb on the slave with firewall
|
|
* - wait 60 seconds
|
|
* - check which slave is used for connection now, expecting any other slave
|
|
* - check warning in the error log about broken slave
|
|
* - unblock mariadb backend (restore slave firewall settings)
|
|
* - check if Maxscale still alive
