[ceph-users] Quincy: failure to enable mgr rgw module if not --force

Hi, I'm trying to use the rgw mgr module to configure RGWs. Unfortunately it is not present in 'ceph mgr module ls' list and any attempt to enable it suggests that one mgr doesn't support it and that --force should be added. Adding --force effectively enabled it. It is strange as it is a brand new cluster, created in Quincy, using cephadm. Why this need for --force? And it seems that even if the module is listed as enabled, the 'ceph rgw' command is not recognized and the help is not available for the rgw subcommand? What are we doing wrong? Cheers, Michel
