Hi all,
Use dm-error to simulate disk errors for written file extents and ensure
that the media scanner in xfs_scrub actually detects them.
v23.1: tidy up some loose ends, make it more obvious in dmerror where the
awk and bash transitions happen
If you're going to start using this mess, you probably ought to just
pull from my git trees, which are linked below.
This is an extraordinary way to destroy everything. Enjoy!
Comments and questions are, as always, welcome.
