Hi Kai,

There are 2 concepts that need to be clarified:

- InnoDB Cluster Metadata
- Group Replication Cluster

If you stop cleanly nodes (member of the Group Replication), the cluster goes from 3/3 to 2/2 and then to 1/1... so it will keep working.
Of course in the metadata you can see that there were 3 nodes configured and 2 are missing.
Group replication doesn't know about the "past" view.

Instead of cleanly stop the nodes, you kill them, then it will be all different and the cluster will behave as you expect.
