this is expected behavior for the metadata consistency model. all
metadata gets created on the metadata master zone first, and syncs to
all other zones in the realm from there. so your buckets will be
visible to every zonegroup
however, ZG2 is still the 'bucket location', and its object data
should only reside in ZG2's zones. any s3 requests on that bucket sent
to ZG1 will get redirected to ZG2 and serviced there
if you don't want any metadata shared between the two zonegroups, you
can put them in separate realms. but that includes user metadata as
well
