Arf no worries. Even after a quick dive into the logs, I haven't find anything. (default log level).

Hi Greg,

Just tried the list watchers, on a rbd with the QEMU driver and I got:

root@ceph:~# rados -p volumes listwatchers rbd_header.789c2ae8944a
watcher=client.30882 cookie=1

I also tried with the kernel module but didn't see anything…

No IP addresses anywhere… :/, any idea?

Nice tip btw :)

Oh, whoops. Looks like the first iteration didn't include IP
addresses; they show up in version 0.65 or later. Sorry for the
inconvenience. I think there might be a way to convert client IDs into
addresses but I can't quite think of any convenient ones (as opposed
to inconvenient ones like digging them up out of logs); maybe somebody
else has an idea...
