The problem of simultaneous success of SetNX in the case of redis cluster cerebral fissure

I want to ask a question:

redis-cluster.

will there be more than one SetNX in the state of brain fissure in redis cluster, all of which return success? For example, when the redis cluster is split into three, and the three cooperative processes are connected to different parts of the brain fissure, SetNX is successful.

does this exist?

because SetNX is used to implement distributed locks, but occasionally multiple cooperators acquire locks at the same time. Will this problem occur in the case of redis cerebral fissure?
