Hi cephers: Recently, I was testing the multisite of rgw(ceph 12.2.5). I have some questions, can you give me a hand? 1. every zone has its own placement-rules. But when I create a bucket, it will be created on all the other zones which requires the zone s have the same placement-rule. So are the placement rules the zone's info or the zonegroup's info? 2. every bucket records its placement-rule and it asks the placement-rule never changed. But we can change the placement-rule easily. So why does not the bucket record the pool's info instead of the placement-rule? 3. the zonegroup has a default placement-rule. Why is the default placement-rule zonegroup-level, not zone-level? Thanks!!!
