No excessive memory usage and no iowait at all. Exactly! And another interesting information (maybe). I have ceph-osd process with big cpu load (as Steve said no iowait and no excessive memory usage). If I restart the ceph-osd daemon cpu load becomes OK during exactly 15 minutes for me. After 15 minutes, I have the cpu load again. It's curious this number of 15 minutes, isn't it? _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
