Could you turn on "debug ms = 1" and "debug osd = 10" prior to restarting the OSDs on one of your hosts and sharing the logs so we can take a look? It also might be worth while to strace one of the OSDs to try to determine what it's working so hard on, maybe: strace -fc -p <osd pid> > strace.osd1.log Thanks! -- Kyle _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
