Hmm, that output is followed by an assert if "mds_verify_scatter" is set to true, and it seems to fix the issue by just resetting all the values to 0 — which is probably also insufficient, Zheng? This also means that you must have enabled the "mds bal frag" option, right Markus? -Greg _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
