Just to make sure I'm working with the right code base, can
you confirm that you're using a kernel built with the equivalent
of what's now in the "wip-nick-newer" branch (commit id 1728893)?
Also, looking at this log I don't think I see any rbd debug output.
Does that make sense to you?
How are you activating debugging to get these messages?
If it includes something like:
echo module libceph +p > /sys/kernel/debug/dynamic_debug/control
it might be that you need to also do:
echo module rbd +p > /sys/kernel/debug/dynamic_debug/control
This information would be helpful in providing some more context
about what rbd is doing that's leading to the various messaging
activity I seen in this log.
Please send me a log with that info if you are able to produce
one. Thanks a lot.
