I was looking into moving buckets owned by a user under a tenant namespace; (a common usecase is in openstack installations where tenant namespaces are preferred with openstack keystone for eg.). Doing this manually with rados and radosgw-admin cli would involve something in the lines of: 1. Copying the user and user.buckets object under the users.uid pool with the tenant$user name with rados cp which seems to preserve omaps 2 radosgw-admin metadata get user:<uid> > uid.json # change uid to reflect the tenant field 3 radosgw-admin metadata get bucket:<bucket-name> modifying the empty tenant field with the tenant info; and owner to the tenant$user format and finally metadata put bucket:tenant/<bucket-name> 4 repeating the same metadata get/put for bucket.instance 5 metadata rm user:<old-username> bucket:<old-bucket-name> bucket.instance:<old-instance> 6 radosgw-admin metadata put < modified-uid.json I'm not sure whether this covers all the bases or any other metadata is left behind? Current RGW Bucket link/unlink does steps 2,3 and getting the ACLs right and correctly adding and removing the omap entries in the user.bucket object, though in the current form it would fail as version checks for a non existent object would fail. Given these complexities would it also make sense supporting this in radosgw-admin? (with the caveat that we want no buckets or user metadata of the concerned user also modified during this time frame) -- Abhishek Lekshmanan SUSE Linux GmbH, GF: Felix Imendörffer, Jane Smithard, Graham Norton, HRB 21284 (AG Nürnberg) -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
