Do mysql master failover only when there are more than one slaves #107
Description
Hi
I have a mysql cluster with one master node and two hot standby slave nodes.
All reads and writes go to master. The three node cluster is managed by
corosync pacemaker that has a VIP for the master node. At any given time at
least two nodes should be up and running for the VIP to be online. Is there a
possibility to do mysql master failover only when there are two slaves in the
mha config. In case of only one slave there should be no mysql failover
performed. One work around could be setting --last_failover_minute to a higher
value for example 1440 minutes but that still wont ensure that the failover
will not happen again when the new master node goes down after
last_failover_minute had passed.
OS: Debian GNU/Linux 7.8 (wheezy)
mysql-server: 5.6.19-1~exp1-log (Debian)
mha4mysql-manager: 0.53-3
mha4mysql-node: 0.53-1
Your response would be greatly appreciated.
