+# DESCRIPTION:
+# dRAID should provide redundancy
+#
+# STRATEGY:
+# 1. Create block device files for the test draid pool
+# 2. For each parity value [1..3]
+# - create draid pool
+# - fill it with some directories/files
+# - verify self-healing by overwriting devices
+# - verify resilver by replacing devices
+# - verify scrub by zeroing devices
+# - destroy the draid pool
