codis: ResponseError: handle request, slot is not ready, may be offline

Background¶

I shut down all the servers where codis is located before my vacation, and restarted codis a year later, and encountered an error during execution:

ResponseError: handle request, slot is not ready, may be offline

Solution¶

1. Allocate slots first
2. Use Migragte Some
