Ramin, I think youre still going to experience what Casey described.
If your intent is to completely isolate bucket metadata/data in one zonegroup from another, then I believe you need multiple independent realms. Each with its own endpoint. For instance; Ceph Cluster A Realm1/zonegroup1/zone1 (endpoint.left) Realm2/zonegroup2/zone2 (endpoint.right) Then, you dont need to bother with location constraint. Attempts to create buckets via endpoint.right will be created at realm2/zonegroup2. Buckets created via endpoint.left will show up at zonegroup1/zone1. They will be completely isolated from one another, yet reside on the same cluster. Location constraint could be used for different placement targets within zonegroup2. For instance, location constraint zonegroup2:put-data-on- replicated-storage or zonegroup2:put-data-on-erasure-storage. Without separate realms, I believe you will continue to experience what Casey explained. If it is your intent to have multiple isolated zonegroups within the same cluster, then I would read through the docs for creating a multi- realm deployment. And just stop short of creating an additional synchronized replicated realm. (step #15) https://www.ibm.com/docs/en/storage-ceph/5?topic=administration-configuring-multiple-realms-in-same-storage-cluster You should then have two independent realms residing on the same cluster. You can further isolate the two zonegroups by deploying new root pools. By default, I believe the zonegroup/zone settings are stored in .rgw.root Any actions without specifying an alternative zonegroup/zone will by default fall under the .rgw.root hierarchy. You could, for example, deploy two new realms, each with its own root pool. zonegroup1 --> .zonegroup1.rgw.root zonegroup2 --> .zonegroup2.rgw.root These two zonegroups will be isolated in their own realms, and also isolated from the default .rgw.root Once you have that setup, it's like each realm is its own completely separate rgw deployment, but reside within a single Ceph cluster. It takes a bit of forethought to get everything set up correctly. You will need to create keys for each realm and be mindful of which realm you are operating on. It may take several attempts to get everything in place the way you expect it to be.
