Redis Sentinel Master syncing

[Tedley Meralus]

Documentation: http://redis.io/topics/sentinel
With my understanding of Redis I can use Sentinel to monitor and handle automatic failover of Redis Master by promoting the slave to master when the master goes down.
Will Sentinel also vote to promote the Master back to Master if the Master comes back up?
I have been testing and haven't been able to get the sentinels to +convert after passing
$ redis-cli -a password1 -p 6380 DEBUG segfault
then
$ /usr/local/bin/redis-server start

Does anyone know if this is possible?

No it does not promote the old master back to master once it is up. It will only do a failover once the new master goes down.

 In your Redis clusters, if an available slave instance exists, sentinel leader will take the process of failover and promote the slave to new master. Old master perhaps restarts after a few time.

Thanks for the confirmation. I thought I had noticed something along those lines before.
