# When a primary election is running, executing an action it will fail
#
# Test:
# 0. This test requires three servers
# 1. Start server1 and bootstrap group
# 2. Configure server2 with weight to be next primary
# 3. Lock table to block primary election
# 4. Start server3
# 5. Insert data to prevent server2 set read only and block on primary
# election
# 6. Stop server1 and run primary election
# 7. Executing an action will fail, a primary election is running
# 8. Unlock table to primary election finish
# 9. Assert server2 is the new primary
# 10. Cleanup
