Hi Scott, I try to reproduce the mirror issue in my local environment. It seems it is due to lack of repodata of " http://mirror.starlingx.cengn.ca/mirror/centos/download.ceph.com/rpm-mimic/e...". If I switch to use original ceph repo which contains the repodata folder, I could download rpms successfully. But my local error message is not the same as CENGN's. This debug data is just for you reference.
