Question: what's the "do not log at all" syntax in ceph.conf? I tried putting everything on "debug xyz = 0", but ceph (osd in this case) is still logging plenty. According to this, I think it shouldn't: # grep debug /etc/ceph/ceph.conf ; logging, for debugging monitor crashes, in order of debug ms = 0 debug mon = 0 debug paxos = 0 debug auth = 0 ; mds logging to debug issues. debug ms = 0 debug mds = 0 debug mds balancer = 0 debug mds log = 0 debug mds_migrator = 0 debug monc = 0 ; osd logging to debug osd issues, in order of likelihood of being debug ms = 0 debug osd = 0 debug filestore = 0 debug journal = 0 Log example: 2011-04-18 01:28:56.787046 7f7976fd8700 osd0 5 pg[1.3d( v 5'186 (5'184,5'186] n=1 ec=2 les=5 3/3/2) [0,1] r=0 mlcod 5'184 active+clean] sending commit on repgather(0x7f794827fb70 applying 5'186 rep_tid=49196 wfack=0 wfdisk= op=osd_op(mds0.1:27067 200.00000058 [write 3241176~1615] 1.fbbd) v2) 0x7f794811b630 Z -- 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
