Hi guys.

Anybody here use Redis and RA and not Redis' Sentinel?
I'm trying to follow what appears as fairly simple man page 
yet I fail to get it all work.
Firstly, RA man page does mention redis.conf in terms of 
replication settings and I wonder - should those bits be 
there as if was typical redis replication setup, with no 

I have follow man page and did:

-> $ pcs resource create p_redis ocf:heartbeat:redis 
op start timeout=300s op monitor interval=5s op monitor 
interval=3s role=Master promotable
(this is with 'replicaof' absent in configs)
HA reporsts:
   * Clone Set: p_redis-clone [p_redis] (promotable):
     * p_redis    (ocf::heartbeat:redis):     Slave
     * p_redis    (ocf::heartbeat:redis):     Master
     * p_redis    (ocf::heartbeat:redis):     Slave

but actually, yes master starts but supposed slaves fail with:

72913:S 06 May 2021 17:08:18.842 * Connecting to MASTER 
72913:S 06 May 2021 17:08:18.843 # Unable to connect to 
MASTER: Resource temporarily unavailable

 From that log snippet I think IP address is missing, should 
be next to port, but I'm not sure, yef if I'm correct then 
that bit should be in 'redis.conf' because RA does not take 
care of that.

Anybody has a working experience or any suggestions which 
can share?
many thanks, L.
