According to this, I think it shouldn't: Hi Zenon, Messages that are output at log level 0 or -1 will always be displayed. I'm not sure if this message belongs at that log level or not-- I haven't dealt with the OSD repop code in a while. In general, I don't think that anyone will ever want to turn off logging completely. That would be a little bit like running your server without syslog. It just doesn't happen in the real world. Also, Ceph is not stable yet, and logs are the main (only?) diagnostic tool we have for most problems. I guess sometimes there is a core file if you've set up your system for that. That being said, we do need to be a lot less verbose in some places. If you find any log messages you think are mis-prioritized, patches are welcome!
