| |
I need some kind of way to fail a single disk partition (hdg8) while the system is running, then reenable it. It doesn't have to be general-purpose and I don't mind doing ugly hacks to the disk code to make it happen.
I was thinking of putting a flag in /proc somewhere, along with some code in generic_make_request like this:
if (proc_fail_the_disk && bh->b_rdev == the_disk) do_something_to_the_request;
What field could I change in the request that would make it fail without causing too many side effects? (I suppose I'd learn a lot by just picking a likely field and whacking it, but I'm not sure I want to try and debug the mess.)
Is this even the right approach at all?
