keepalived + redis failover

[sevmax]

Hi,
I'm working on running 2 redis nodes as failover cluster.
Keepalived migrating VirtualIP successfully, but still not clear how to run command on slave to be a master during failover.

Here is a config:

! Configuration File for keepalived

global_defs {
   notification_email {
        root@example.com
   }
   notification_email_from redis1_keepalived@example.com
   smtp_server 127.0.0.1
   smtp_connect_timeout 30
   router_id keepalived_on_redis
}

vrrp_script chk_redis {                                 
    script "kill -0 `cat /var/run/redis.pid`"       
    interval 2                                          
}

vrrp_instance VI_1 {
    state MASTER
    interface bond0
    virtual_router_id 10
    priority 101

    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 12345678
    }
    virtual_ipaddress {
        1.2.3.4 label bond0:0
    }
    track_script {
           chk_redis
    }

notify_fault "redis-server /etc/redis.conf; redis-cli slaveof no one"
}

Please advice how to configure master/slave to run redis-cli command properly on failover and then restore slave status on restoring master. Thanks!
