Hi, I'm Wenjun Jing from China Mobile(suzhou). Recently ceph multisite is applied to our production onest, short for Object-Orient Storage System, which is a object storage production based on ceph. Needless to say, the feature of active-active is awesome! But there are also some features which may not be supported very well and the community is improving them constantly. So we want to discuss with you to comfirm the roadmap of them. This is the fact that if creating bucket on the secondary zone/zonegroup. The request would send to meta master and the bucket will be created on meta master firstly, then it will be created locally. Some metadata/feature of bucket in the process upper is not synced to secondary zone or zonegroup. For instance, the bucket acl and bucket versionning cannot be modified on the slave zone/zonegroup, which has been fixed in the jewel. Now, we want to ack you to get the development direction(way) of the bucket metadata to modify. The below are some ways which I've thought out currently. 1. All the bucket metadata will be modified in the meta master firstly and then modify the metadata locally according to the status retured from meta master. Considering this way, some metadata (eg. creation time) may not consistent with the meta master, which doesn't improve user experience. 2. All the bucket metadata will be modified in the meta master firstly and sync the changed bucket metadata to slave zone or zonegroup. 3. The other alternative way to handle this situation? Could you discribe to me detailedly? Once the upper way could be comfirmed Definitely, we can make some contribution to the community. Look forward to your kind reply.
