When you made a bucket creation request, did you specify the placement-target? I think we need to pass it in the request as well.
>From blog[1]:
"Data placement pool is define in this order :
from the request (“bucket location”)
from user (“default_placement” : see with radosgw-admin metadata get user:<uid>)
from region map (“default_placement”)"
