FWIW, it seems to work just fine, even RAID1 across usb-storage
drives -- which do spin down despite the ext3 filesystem on them.
But they're mounted as /store, and there's nothing writing there.
This is with a lenny system and 2.6.26 kernel.
If you are trying to make it work for the main system, make sure you
use something like laptop-mode, or at least tune the parameters,
disable logging etc., and turn the atime option off for all your
filesystems.
