Thanks for the patches!

> This does not include any of the provenance support.  It just allows you
> to modify distribution, distribution parameters, and number of datafiles
> to use for a given directory.  These settings will only impact the
> creation of future files within the directory; it does not change
> parameters for existing files.

> [user at node]$ setfattr -n "user.pvfs2.num_dfiles" -v "1" /mnt/pvfs2/directory
>
> [user at node]$ setfattr -n "user.pvfs2.dist_name" -v "basic_dist"
> /mnt/pvfs2/directory
>
> [user at node]$ setfattr -n "user.pvfs2.dist_params" -v "strip_size:4096"
> /mnt/pvfs2/directory

Can you also add an entry in the FAQ for these if you haven't done it
already?

This is pretty neat!
Thanks again,
