I have 3 ceph clusters on nautilus 14.2.9 (same configuration through puppet). 2 of them are autmatically sharding rados buckets, one of them is not When I do radosgw-admin reshard stale-instances list on the cluster where it does not work I get: reshard stale-instances list Resharding disabled in a multisite env, stale instances unlikely from resharding These instances may not be safe to delete. Use --yes-i-really-mean-it to force displaying these instances. The other 2 clusters don't give this warning. They are all single site. The out put of realm list, zonegroup list and zone list for the cluster that fails auto sharding are as follows realm list { "default_info": "e724bd71-31eb-45c8-a456-151f6a5aa8b5", "realms": [ "backup" ] } zonegroup list { "default_info": "ce4329ae-2bc8-4117-9b82-271022b223fa", "zonegroups": [ "dc3" ] } zone list { "default_info": "7f9bebd6-a9cf-4006-83b1-ff99391aacc0", "zones": [ "dc3-r1" ] } mgr configuration (default value) rgw_dynamic_resharding true How does ceph determine whether it is single site or multi site? How can I force the automated bucket sharding?? Any help would be much appreciated Marcel
