Copying a pool sometimes is useful, even with those limitations. Until there is an alternative way to do the same I would not remove this. A better approach to me is to move this functionality to something like `ceph_radostool` (people use such tools only when facing extraordinary situations so they are more careful and expect limitations). -- Mykola Golub _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
