Could be 11, could be 10, could be 1334454. The number itself doesn’t mean anything; it’s just a number.

Show us the contents of runtime\_mysql\_galera\_hostgroups / mysql\_galera\_hostgroups tables. That will tell you which HG is which.

Yes, there should only be 1 writer in HG11 which should be a setting in the above table.
