oh hey, we've got an estimated 1.7 billion inodes in production right now.
of course, they're not *all* active, nor are they all on the same server... :)
it is scary though. filesystems and tools don't really scale well to this size at the moment. you certainly don't want to do more than several million inodes on one fs -- otherwise you start running into insane backup difficulties plus unacceptably long fsck times. (of course we use a logging fs -- but at scale, you produce filesystem corruption on a regular basis regardless what the filesystem/os/hardware is, and fsck time determines downtime some users might experience.)
mmm. scaling. it's such a wonderful problem space.
