I am running a 4 node REDIS CLUSTER on a Windows 2012 box.
My set up is 1 Master and 3 Slaves. When I end the Master Service via the Services component, none of my slaves autopromote themselves to master. How do I get the Slaves to recognize a Master is failing and have them promote as soon as they see the failure. Below is my Redis Config. This is the same Config file for all nodes, the only difference is the port is changed for each node
port 30002
cluster-enabled yes
cluster-config-file nodes.conf
appendonly yes
loglevel notice
logfile "log"
syslog-enabled yes
syslog-ident redis
maxmemory 200mb
maxmemory-policy volatile-ttl
Edit
What other information do I need to supply to make this easier to help fix.
Edit 2
My end game is a redis cluster , I want this Cluster to have 1 master and 3 slaves. The reason why I want a cluster over a setup with 1 Master and 3 slaves is, I want to avoid installing REDIS Sentinel. I want the cluster to promote the slaves to masters and not redis sentinel doing that.
My Install process is as follows
voila cluster setup with with FOLDER A being the master and B,C,D being slaves of A. Now the only problem is, when A goes down none of the slaves (B,C,D) auto promote.
EDIT
redis.conf file of the master
port 30001
cluster-enabled yes
cluster-config-file nodes.conf
appendonly yes
loglevel notice
logfile "log"
syslog-enabled yes
syslog-ident redis
maxmemory 200mb
maxmemory-policy volatile-ttl

As far as I know, redis cluster will not work with less than 3 masters.
Take a look at this note on redis cluster tutorial:
Note that the minimal cluster that works as expected requires to contain at least three master nodes. For your first tests it is strongly suggested to start a six nodes cluster with three masters and three slaves.
