ERR Slot xxx is already busy (Redis::CommandError)

Question

I want setup redis cluster with 6 nodes (node1, node2, node3, node4, node5, node6), which has 3 masters and 3 slaves. Each node has this configuration file

redis.conf

port 6379
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 10000
appendonly yes

I get error when create the cluster. Create command:

redis-trib.rb create --replicas 1 node1:6379 node2:6379 node3:6379 node4:6379 node5:6379 node6:6379

Error:

Can I set the above configuration? (type 'yes' to accept): yes

I also did these, but also got same error message

1. use ip address instead of hostname
2. remove nodes.conf in each nodes

Answer 1

How said @thepirat000 (in all nodes did FLUSHALL and then CLUSTER RESET SOFT) i also changed hostname to ip address
