Adding test case : test_client_side_quorum_with_fixed_for_cross3
Description: Test Script to verify the Client Side Quorum with fixed for cross 3 volume * Disable self heal daemom * set cluster.quorum-type to fixed. * start I/O( write and read )from the mount point - must succeed * Bring down brick1 * start I/0 ( write and read ) - must succeed * Bring down brick2 * start I/0 ( write and read ) - must succeed * set the cluster.quorum-count to 1 * start I/0 ( write and read ) - must succeed * set the cluster.quorum-count to 2 * start I/0 ( write and read ) - read must pass, write will fail * bring back the brick1 online * start I/0 ( write and read ) - must succeed * Bring back brick2 online * start I/0 ( write and read ) - must succeed * set cluster.quorum-type to auto * start I/0 ( write and read ) - must succeed * Bring down brick1 and brick2 * start I/0 ( write and read ) - read must pass, write will fail * set the cluster.quorum-count to 1 * start I/0 ( write and read ) - read must pass, write will fail * set the cluster.quorum-count to 3 * start I/0 ( write and read ) - read must pass, write will fail * set the quorum-type to none * start I/0 ( write and read ) - must succeed Change-Id: Ic159aee3ca80f6a584a46e2ac7986f4007346968 Signed-off-by: Vijay Avuthu <vavuthu@redhat.com>
