Goal

 When creating an InnoDB Cluster the following error appears:

The dba.createCluster() function fails if used on an instance with innodb_page_size=4k, because the instance_name column of the instances table in the InnoDB Cluster metadata uses a VARCHAR of size 256, which is too large for the innodb_page_size=4k. However, the size of this column cannot be changed because it is used to hold hostnames of the cluster members which can have a length up to 255 bytes.
