What do you want to learn? What Ceph features are you interested in

Hi all,
I'm in the process of testing out ceph on a small cluster. The cluster
is virtually empty with no clients, just a few OSDs. I noticed extensive disk
write I/O on some nodes and tracked them down to the ceph-mon daemon. A cursory
log over 1 hour shows that each monitor generates
