Run xfs_repair twice at the end of each test -- once to rebuild
the btree indices, and again with -n to check the rebuild work.

Won't this hide fs corruptions? Did I miss anything?

Thanks,
Eryu

I could've sworn it did:

xfs_repair -n
(complain if corrupt)

xfs_repair

xfs_repair -n
(complain if still corrupt)

But that first xfs_repair -n hunk disappeared. :(

Ok, will fix and resend.

Not sure this is the best idea - when repair on an aged test device
takes 10s, this means the test harness overhead increases by a
factor of 3. i.e. test takes 1s to run, checking the filesystem
between tests now takes 30s. i.e. this will badly blow out the run
time of the test suite on aged test devices....

What does this overhead actually gain us that we couldn't encode
explicitly into a single test or two? e.g the test itself runs
repair on the aged test device....

Cheers,

Dave.

I'm primarily using it as a way to expose the new rmap/refcount/rtrmap btree
rebuilding code to a wider variety of filesystems.  But you're right, there's
no need to expose /everyone/ to this behavior.  Shall I rework the change
so that one can turn it on or off as desired?
