I see it's the undocumented "ceph.dir.layout.pool"
Something like:
setfattr -n ceph.dir.layout.pool -v mynewpool <DIR>
On an empty dir.... should work. I'd like one directory to be more heavily
mirrored so that a) objects are more likely to be on a less busy server b)
availability increases (at the expense of size/write speed).

Nothing official at this point. Sébastien wrote a short blog about it
earlier this year that will give you the basics:
http://www.sebastien-han.fr/blog/2013/02/11/mount-a-specific-pool-with-cephfs/
But at this point it's easier to use the virtual xattrs at
"ceph.dir.layout", as shown in this ticket:
