Hi list, I'm learning Ceph CRUSH map and know that the bucket ID is optional and can be **changed** if you like. By default, if bucket ID hasn't been configured, then ceph will assign one automatically to the bucket. When considering to manage a production ceph cluster, we'd like to create some custom crush map, so as bucket ID, like: host ID range [1, 100] rack ID range [101, 200] datacenter ID range [201, 300] ... rather than left ID assigned by ceph automatically. Please help me to understand if it's valuable to manage bucket ID myself or just let it go. Thanks in advance! -- Thanks, Chengwei
