(03:51:58 PM) bchrisman: can we control the mds logging to perhaps only
output locking requests?
(03:52:05 PM) bchrisman: or rather.. any lock activity?
(03:52:31 PM) bchrisman: trying to debug an issue where it looks like we
have a bum lock# but putting mds=20 spams our logfiles
(04:01:35 PM) cmccabe: bchrisman: I don't see any configuration setting
that directly corresponds to that
(04:02:26 PM) bchrisman: I guess I'll check whether lockign has a specific
debug level, or if 20 is the only way to get it.
(04:03:36 PM) cmccabe: I see some log output in Locker.cc
(04:03:43 PM) cmccabe: perhaps you will want to change the levels of that
This should do the trick. We do the same for MDLog.cc and MDBalancer.cc
already.
