The mons in my production cluster have a very high cpu usage 100%. I think it may be caused by the leveldb compression. How yo disable leveldb compression ? Just add leveldb_compression = false to the ceph.conf and restart the mons? Thanks a lot! _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
