# This test checks that if a joiner has rule that makes it incompatible with
# another member in the group it wont be able to join it.
#
# To test this:
# 0. The test requires two servers: M1 and M2.
# 1. We bootstrap GROUP with M1, and add some data for recovery.
# 2. Try to start M2 where we added a fake rule that makes it incompatible
# with the group. Start GR should fail.
# 3. Restart M2 to have clean compatibility settings post clearing the
# incompatibilty rule. Start GR should succeed.
# 4. Check M2 has all the data.
# 5. Clean up.
