I'm working on http://tracker.newdream.net/issues/3342 and was able to
reproduce the msgr bug (some annoying msgr race I think) while generating
full libceph debug output. I used a teuthology yaml fragment like so:
tasks:
- clock: null
- ceph:
log-whitelist:
- wrongly marked me down
- objects unfound and apparently lost
- thrashosds: null
- kclient: null
- exec:
client.0:
- echo 'module libceph +p' > /sys/kernel/debug/dynamic_debug/control
- workunit:
clients:
all:
- suites/ffsb.sh
I was pleasantly surprised that even though this is putting copious
amounts of crap in dmesg it didn't slow things down enough to avoid
tripping the bug. And the 'dmesg' command in kdb appears to be working
now (a couple months back it wasn't). Yay!
Anyway, this might be useful in tracking down other bugs as well...
