You're looking for:
virsh pool-refresh POOLNAME

It should not have any ill-effects if you have libvirt >= 0.6.3. It is
designed to be allowed to be restarted at any time & re-sync its state
upon startup.
NB, there should be no need to ever restart libvirtd for anything other
than changes to /etc/libvirt/libvirt.conf, or /etc/libvirt/qemu.conf.
Everything else should be able to be handled via SIGUP (service libvirtd
reload), or virsh commands like pool-refresh.
