It sounds to me like another manifestation of
https://launchpad.net/bugs/1268732 which we're addressing through
several patches which hit much of what you suggest:

 * https://review.openstack.org/68782 (don't copy logs to /home)

 * https://review.openstack.org/68990 (git clones in /opt)

 * https://review.openstack.org/69075 (make query logging optional)

Not particularly trivial without a reboot, since getting file
descriptors closed out on /var at a multi-user runevel is, well, not
something I've ever had much luck at.

Not just painful, but mostly impossible. Our providers give us a
tiny block device formatted and mounted as the root filesystem, plus
a large ephemeral block device which we partition into /opt and swap
when building a node from a snapshot.
