cluster setslot <slot> migrating node_id just set the migrating status, you need use migrate command, cluster-setslot give a detail description

thinks for your answer，but when i use the migrating to move the key , it tell us 192.168.208.31:6379> MIGRATE 192.168.208.32 6385 "foo" 0 1000 REPLACE -> Redirected to slot [12182] located at 192.168.208.32:6384 (error) ERR Target instance replied with error: NOAUTH Authentication required. i have already use the -a option with the password, thinks.....

Comment From: badboy

MIGRATE does not support authentication. There is no other way than to disable it

Comment From: liuwenru

thinks for all the pople that help me, i can move it , but how can i MIGRATE date with the cluster node that use password?

Comment From: badboy

You can't.

You could try to work around it by manually issuing DUMP, connect to the receiving instance and call RESTORE. This has to happen from your client.

Comment From: liuwenru

ok, when i create a cluster , can i set the node id，because i want use it in docker， thinks！

Comment From: badboy

No, the Node ID is randomly chosen at start. There's no (safe) way to pre-generate it.

Comment From: kd-devops

Just wanted to cross check, weather authentication issue (Error: NOAUTH) with Migrate has been fixed or its still have same issue.

I am using redis-4.0.6 with redis-trib-pass.rb and still facing issue while doing redis-trib-pass.rb reshard

[ERR] Calling MIGRATE: ERR Target instance replied with error: NOAUTH Authentication required.

I am passing password using auth flag:

Command Executed :

redis-trib-pass.rb reshard --auth host:ip

Weird thing is, this error only comes when cluster nodes has keys ...for empty slots (slots with no key) resharding works fine.

Any suggestion please ?

This issue is about migrate with auth, so it's a duplicate of #3508.
