*** Please fix your cluster problems before resharding

redis-trib has a fix subcommand. Did you try it?

[qunchenmy]

I Know。
But I wonder what has happened to cluster? no other operations.

Somehow one slot is still in importing state. Without knowing what you did, it's impossible to say why it is that way.

Perhaps you had tried moving slot once before that but it should have failed.
I think that importing state had remained in that case.
Anyway, you can fix your problem as below.

% ssh 192.168.44.189
% redis-cli -p 6631 CLUSTER SETSLOT 12927 STABLE
