[QUESTION] Moving keys from the wrong shard

[pavel-krush]

After errors during cluster scaling one of cluster's nodes became inconsistent. Some keys of one particular slot have remained on the old shard.

We have restored all the data, but keys are still on the wrong shard. SCAN returns them, but any other command returns MOVED error:

redis-cli -h 10.222.122.7

Is there any way to just delete these keys without heavy migration procedures and without removing the node from the cluster?
