Adding testcase: Negative test - Exercise Add-brick command
This testcase covers below scenarios, 1) Add-brick without volname 2) Adding a duplicate brick 3) Adding a brick which is already part of another volume 4) Adding a nested brick i.e brick inside another brick 5) Add a brick to a non existent volume 6) Add a brick from the peer which is not in cluster Change-Id: I2d68715facabaa172db94afc7e1b64f95fb069a7 Signed-off-by: Prasad Desala <tdesala@redhat.com>
