That should all on a per-disk configuration. I would like a different, configurable spin-down timeout (optionally never) for each disk.
A required feature IMHO: there should _never_ be dirty blocks for disks that are not spinning.
Maybe it is possible to internally remount RO file systems that have data on the disk before spinning down. Should not be much of a problem if the file system is mounted with noatime and there aren't any files open for writing nor directory operations in progress.
I'd rather have open() blocking and not fill all the memory with dirty buffers that need to wait for spin-up to complete before they can be written.
Swap areas, direct access to block device. loop devices and raid partitions may be more difficult but you get the idea...
