Oh,no!My redis cluster master-slave relationship is lost

[gyl362500123]

From China,
The Redis cluster is deployed in the k8s container. When I restart the redis cluster (at this time, the pod IP has changed), the master-slave relationship is lost occasionally. However, through the command 'cluster Info', you can see that the cluster status is OK, and 'cluster nodes' can also see that the IP of redis has changed.
I don't know why. What could be the reason?
Normal condition:

Abnormal condition: You can see that the slave node of some master nodes are gone

ip change logs recorded in different redis.log logs





The slave node is trying to reconnect to the old master IP

Who has some opinions？
