Hmmmm. A quick look at the linux code makes me thikn that background
writeback on linux has never been able to cause a shutdown in this case.
However, the same error on Irix will definitely cause a shutdown,
though....
 I hope Linux will follow Irix, that's a consistent standpoint.
I raised a bug for this yesterday when writing that reply. It won't
get forgotten now....
 David, have you a plan to implement your "reporting raid5 block layer"
 idea?  No one else has caring about this silent data loss on temporary
 (cable, power) failed raid5 arrays as I see, I really hope you do at least!
Yeah, I'd love to get something like this happening, but given it's about
half way down my list of "stuff to do when I have some spare time" I'd
say it will be about 2015 before I get to it.....

Cheers,

Dave.
