# Consistency Checker

This folder implements a consistency checker as described in the [redis cluster tutorial documentation][tut] and implemented in the [reference redis cluster client ruby repository][rubycluster].

The `redis-trib.rb` and `create-cluster` scripts are from the [redis repository][redis] and copied here only for convenience, with the redis copyright added to the top of the files. The `create-cluster` script has been adjusted to start the $PATH-installed redis-server and redis-cli binaries, and the `redis-trib.rb` script in the current directory.

All scripts should be executed in this directory.

To run the cluster:

1. create-cluster start
2. create-cluster create (type yes when prompted)
3. execute the ccheck go client program
4. play with the cluster, trigger failovers, etc.
5. create-cluster stop
6. create-cluster clean
