Hi Ted,

Thank you for replying, again.

What are you trying to _do_ by, at the high level?

It should do what you want, but at this point I'm wondering _why_ you
want to do it, and whether or not it is something you _should_ be
doing.

I probably have an odd usecase. I am trying to evaluate whether a new
storage stack (i.e., a virtual disk) is good enough for running an
application service; the service can frequently encounter crash
reboots, and the storage stack should be reliable enough. After
testing the service out on the new stack for a while with induced
crash-reboots, I began to suspect corruption in the stack, probably
caused during crashes. I was hoping I could catch the corruption
early-on, and make the testcase more repeatable, if I used "fsck -f"
during the testing. The other ideas I tried out to detect corruption
(like adding data checksums within the service) were funnily even
harder to get right.

Thanks,
Thanu
