[ceph-users] Ceph repo is broken, no repodata at all

Hi list, I found that ceph repo is broken these days, no any repodata in the repo at all. http://us-east.ceph.com/rpm-jewel/el7/x86_64/repodata/ it's just empty, so how can I install ceph rpms from yum? A workaround is I synced all the rpms to local and create repodata with createrepo command,

[ceph-users] Should I manage bucket ID myself?

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
