+# DESCRIPTION:
+#	Import with missing log device should not remove spare/cache.
+#
+# STRATEGY:
+#	1. Create a pool.
+#	2. Add spare, cache and log devices to the pool.
+#	3. Export the pool.
+#	4. Remove the log device.
+#	5. Import the pool with -m flag.
+#	6. Verify that spare and cache are still present in the pool.
