# 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.
