The standard response on the mailing list for this issue is to
temporarily add an additional device to the filesystem (even e.g. a 4GB
USB flash drive is often enough) - this will add space to allocate a few
new chunks, allowing the balance to proceed. You can remove the extra
device after the balance completes.
