Hi
I'm currently using Ceph version 16.2.7 and facing an issue with bucket creation in a multi-zone configuration. My setup includes two zone groups:
ZG1 (Master) and ZG2, with one zone in each zone group (zone-1 in ZG1 and zone-2 in ZG2).
The objective is to create buckets in a specific zone group (ZG2) using the bucket constructor. However, despite setting the desired zone group (abrak) in the request, the bucket is still being created in the master zone group (ZG1). I have defined the following endpoint pattern for each zone group:
s3.{zg}.mydomain.com
I am using the s3cmd client to interact with the Ceph cluster. I have ensured that I provide the necessary endpoint and region information while executing the bucket creation command. Despite my efforts, the bucket consistently gets created in ZG1 instead of ZG2.
this is expected behavior for the metadata consistency model. all metadata gets created on the metadata master zone first, and syncs to all other zones in the realm from there. so your buckets will be visible to every zonegroup however, ZG2 is still the 'bucket location', and its object data should only reside in ZG2's zones. any s3 requests on that bucket sent to ZG1 will get redirected to ZG2 and serviced there if you don't want any metadata shared between the two zonegroups, you can put them in separate realms. but that includes user metadata as well
- Ceph Version: 16.2.7 - Zone Group 1 (ZG1) Endpoint: http://s3.zonegroup1.mydomain.com - Zone Group 2 (ZG2) Endpoint: http://s3.zonegroup2.mydomain.com - Desired Bucket Creation Region: zg2-api-name
have reviewed the Ceph documentation and made necessary configuration changes, but I have not been able to achieve the desired result.I kindly request your assistance in understanding why the bucket constructor is not honoring the specified region and always defaults to ZG1. I would greatly appreciate any insights, recommendations, or potential solutions to resolve this issue.
Thank you for your time and support.
--------------------------------- Here are the details of my setup: ---------------------------------
```sh s3cmd --region zg2-api-name mb s3://test-zg2s3cmd info s3://test-zg2s3://test-zg2/ (bucket): Location: zg2-api-name Payer: BucketOwner Expiration Rule: none Policy: none CORS: none ACL: development: FULL_CONTROL ```
this is my config file:
```ini [default] access_key = <KEY> secret_key = <SECRET> host_base = s3.zonegroup1.mydomain.com host_bucket = s3.%(location)s.mydomain.com #host_bucket = %(bucket)s.s3.zonegroup1.mydomain.com #host_bucket = s3.%(location)s.mydomain.com #host_bucket = s3.%(region)s.mydomain.com bucket_location = zg1-api-name use_https = False ```
