CLUSTERDOWN Hash slot not served

[bjorntj]

I am trying to use this operator to create Redis clusters but I seem to have a problem and I am not sure if there is something wrong in my config or something I am missing or?
I have tried to create 2 Redis clusters now, in 2 separated Openshift clusters, using image version 7.2.7.
Both clusters seemed to be created without any issues. But when I open a terminal to one of the Redis pods and try to run

redis-cli -c set tony stark

I get the following error: CLUSTERDOWN Hash slot not served.

After a bit research, I found out that I can fix this by running

redis-cli --cluster fix localhost:6379

But I am guessing that running this fix after everytime I create a cluster should not be needed.

So does anyone have an idea what I am doing wrong here?
(any config you want to see?)
