I have (some of(*)) the disks in my 8-drive RAID-1 btrfs array set
to spin down after 10 minutes of no use. I've not had a problem with

--- If it ain't broke
switch storage types on the fly, so you could at least
start with RAID-1, and then restripe to RAID-5 (or -6) when it's
stable enough for you. This assumes that you can manage to use RAID-1
in the first place and expand later.

to the metadata trees through
the TREE_SEARCH ioctl. It should be possible to walk through the
extents of a given file, and (I think) follow back-refs from the
extent back to the other files that share it.
There's no simple code to do that right now, though.
