Since this is so easily reproduced for you, I would suggest that you next get higher debug logs (debug_mds=20/debug_ms=1) from the MDS. And, since this is a segmentation fault, a backtrace with debug symbols from gdb would also be helpful. -- Patrick Donnelly _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
