for the record i tried both ways to configure: ``` radosgw-admin zonegroup get --rgw-zonegroup="dev" | \ jq '.hostnames |= ["dev.s3.localhost"]' | \ radosgw-admin zonegroup set --rgw-zonegroup="dev" -i - ``` ``` ceph config set global rgw_dns_name dev.s3.localhost ``` Am Mi., 21.

Hi folks,

i just try to setup a new ceph s3 multisite-setup and it looks to me that dns-style s3 is broken in multi-side as wehn rgw_dns_name is configured the `radosgw-admin period update -commit`from the new mebe will not succeeded!

it looks like when ever hostnames is configured it brakes on the new to add cluster https://docs.ceph.com/en/reef/radosgw/multisite/#setting-a-zonegroup

Thanks for any advice! Ansgar
