This is what I get when I stop the master.

...and it continues like this.
This is a test using localhost. I've tried to use one maser and one slave and one master and two slaves, but the output is the same.

This is my redis.conf file:

port 1234
cluster-enabled yes
cluster-config-file nodes1.conf
cluster-node-timeout 5
appendonly yes

The other redis.conf files are just like this, but the port and the config-cluster-file are different.

This is the cluster nodes output on the slave before the failure:

redis 127.0.0.1:1235> cluster nodes

This is the cluster nodes output on the slave after the failure:
