If you have the kernel source installed, you will find several documents relating to I/O schedulers in the Documentation/block directory. It was through these documents that I discovered the ionice command, which only applies if you are using CFQ as an I/O scheduler. Alas, I am still looking for more information on CFQ tuning.
Yes, I use ionice. But it is not very usefull, only root can use it. For instance, I have to copy large files, and I'm not really interested in doing it fast, rather to be able to keep working on something else at the same time. So, I fire the copy, find out the pid, then as root I re-io-nice it. That should not require root priviledges. But your idea of changing the scheduler for a whole device sounds curious. I usually find kernel documents made for developpers to understand, much is assumed to be known already by the reader. There is only one file that talks about ionice, and not much. - -- Cheers, Carlos E.
