Hi, as I had the same issue in a little virtualized test environment (3 x 10g lvm volumes) I would like to understand the 'weight' thing. I did not find any "userfriendly explanation" for that kind of problem. The only explanation I found is on http://ceph.com/docs/master/rados/operations/crush-map/ : "specify a weight relative to the total capacity/capability of its item(s) ... Items may have a weight that reflects the relative weight of the item." Can someone point me in the right direction ? --- Jan _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
