From 8da56d2b135a003df689f271c93367f9a915fa87 Mon Sep 17 00:00:00 2001 From: Prasad Desala Date: Thu, 1 Feb 2018 19:42:14 +0530 Subject: Rebalance: starting and stopping the volume while rebalance is in progress This testcase verifies, volume stop should not be allowed while rebalance is in-progress and it should throw appropriate error.
