Hi Matthieu,
You are talking about associating the *files* within a directory to a
particular set of servers, right (rather than the directory itself)?
If so, then yes, I think that is correct unless something has changed in
more recent OrangeFS releases. The custom layout functionality wasn't
implemented with as many bells and whistles as the custom distribution
stuff.
thanks,
-Phil

Good to know. So there is no way to associate a particular directory to a

Just a heads up on something to look out for: if I recall correctly you
can set the distribution and its parameters on a directory (and it will
then apply to newly created files in that directory), but the same might
not be true of layouts. You might have to specify the layouts
explicitly at create time rather than inheriting them from directory hints.

Matthieu,
You can look in the source tree at src/apps/admin/pvfs2-xattr.c for an
example of using the PVFS_sys_seteattr function call to set
attributes.
Hope that helps!

Hi,
I'm reading this page:
http://www.orangefs.org/trac/orangefs/wiki/Distributions
Could you give me an example of how to change the layout of an existing
directory using PVFS_SYS_LAYOUT_LIST and the PVFS API (instead of setfattr)?
Thanks,
Matthieu
