Test rebalance hang after stop glusterd on other node
1. Trusted storage Pool of 2 nodes 2. Create a distributed volumes with 2 bricks 3. Start the volume 4. Mount the volume 5. Add some data file on mount 6. Start rebalance with force 7. stop glusterd on 2nd node 8. Check rebalance status , it should not hang 9. Issue volume related command Change-Id: Ie3e809e5fe24590eec070607ee99417d0bea0aa0 Signed-off-by: Mohit Agrawal <moagrawa@redhat.com>
