+#
+# Tests that fail-over works correctly for Halo Geo-replication
+#
+# 1. Create a volume @ 3x replication w/ halo + quorum enabled
+# 2. Write some data, background it & fail a brick
+# 3. The expected result is that the writes fail-over to the 3rd
+#    brick immediatelly, and md5s will show they are equal once
+#    the write completes.
+# 4. The mount should also be RW after the brick is killed as
+#    quorum will be immediately restored by swapping in the
+#    other brick.
