Hi, I am using linux 2.6.8 for my research on raid systems. I need to have the disks of an array out of sync for a while. I want to be able to stop a disk request queue (blk_stop_queue) and start it sometime later. Meanwhile its mirrors should be serving r/w as if this mirror was up. Whenever the stopped mirror comes back it will serve all the requests already sent to it. I am queueing up the requests sent to all others while my mirror queue is stopped. The problem is that the other mirrors stop serving as well. Even if I don't stop the queue, only delay its request a little bit, still the others also slow down. Question: how do I get raid to allow mirrors to be out of sync? Obviously, I am missing something out in the code. Any clues?
