[Test] Change the reserve limits to lower and higher while rebal in-progress
1) Create a distributed-replicated volume and start it. 2) Enable storage.reserve option on the volume using below command, gluster volume set storage.reserve 50 3) Mount the volume on a client 4) Add some data on the mount point (should be within reserve limits) 5) Now, add-brick and trigger rebalance. While rebalance is in-progress change the reserve limit to a lower value say (30) 6. Stop the rebalance 7. Reset the storage reserve value to 50 as in step 2 8. trigger rebalance 9. while rebalance in-progress change the reserve limit to a higher value say (70) Change-Id: I1b2e449f74bb75392a25af7b7088e7ebb95d2860 Signed-off-by: “Milind <“mwaykole@redhat.com”>
