Some things you might try:
- backport the #7450 patch to 2.0 and have a custom Cassandra build with
that fix (unfortunately the patch is not currently mergeable)
- upgrade to 2.1 if you can
- create a program that calculates primary ranges of each node from the
ring, and execute repairs on them with --local, -start-token and
--end-token options of nodetool
