So these files change, dynamically, and _all_ cluster nodes need to
know about it? Or are the files just expected to move along with the

If the former, one possible approach is to put all files on central
storage (say, an NFS mount point), and then use ocf:heartbeat:symlink
to manage symlinks where your services expect to find the config

If the latter, you can slap everything on DRBD, and mount the
DRBD-backed filesystem wherever your resource is active. You may, of
course, combine this with managed symlinks.
