Hi, all In our documentation, it says that: Ceph’s logging levels operate on a scale of 1 to 20, where 1 is terse and 20 is verbose. http://docs.ceph.com/docs/master/rados/troubleshooting/log-and-debug/#subsystem-log-and-debug-settings But, it seems that there are some logging levels 25 : mds/MDBalancer.cc:276: dout(25) << "=== got heartbeat " << m->get_beat() << " from " << m->get_source().num() << " " << m->get_load() << dendl; mds/CInode.cc:4189: dout(25) << __func__ << dendl; mds/MDCache.cc:11656: //dout(25) << "saw depth " << d << " " << *dir << dendl; mds/MDCache.cc:11666: //dout(25) << " saw sub " << **p << dendl; mds/journal.cc:373: dout(25) << "EMetaBlob::add_dir_context(" << dir << ") maybe " << So, shoud we update our documentation, or update logging level to 20? -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
