Hi everyone, I'm playing around with the possibility of using Pacemaker in a Redis master/slave cluster. The difficult part of this, is that Redis will not automatically flip itself from read-only slave mode into master mode. A client needs to connect to the slave server and run this SLAVEOF NO ONE<http://redis.io/commands/slaveof>command to turn it into a master.
If I set up a master/slave primitive, is it possible to fire an event script during a failover event that would allow me to do this? After the stonith event fires and the broken master reboots, I would write in something special in the Redis init.d script to detect if my peer is already a master, and start up in slave mode. Has anyone else worked up a cluster config with Redis? Thank you, --Cal
