+# FS QA Test No. 932
+#
+# Test log recovery with repeated (simulated) disk failures. We kick
+# off fsstress on the scratch fs, then switch out the underlying device
+# with dm-error to see what happens when the disk goes down. Having
+# taken down the fs in this manner, remount it and repeat. This test
+# is a Good Enough (tm) simulation of our internal multipath failure
+# testing efforts.
