Did you make the change in the config file used by the client? It looks like maybe you did it on the host machines but not the client ones or something. The kernel client has a whole different set of debug configs; it does not respect the userspace options. To use its debugging you'll need a kernel with debugfs; I think there are some details on it in the Ceph docs. -Greg Software Engineer #42 @ http://inktank.com | http://ceph.com _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
