Folks, I have been looking at the raid1.c code. There is a kernel thread raid1d that could be scheduled on processor A. Then on processor B, other raid code could be scheduled as per each block I/O request. The particular critical section is the usage of the conf variable, and specifically conf->mirrors. raid1d reads conf->mirrors[x] while other parts of the md code alter it simulatenously. Is this a bug? It might explain how people see counts get out of wack on the media...
