No, I''m afraid not.  We are only solving this with per-directory
striping defaults, and it seems you''re just a touch too early to do
exactly what you want.

You should expect to see this functionality in a release sometime this
month, whether it''s part of 1.2.x or 1.4.x.

That feature is planned, and mostly implemented, but not yet integrated.

This will be present in Lustre 1.4 for sure, and maybe in a future 1.2.x
drop.  It depends on how soon that code makes it through the regression
test machine and into a stable branch.

Thanks.

Is there any way to create directories that have different striping
parameters without creating multiple Lustre file systems?  For instance,
could I have two lovs, each with different striping configurations, served
by the same MDS but mounted at different locations on the clients and
possibly served by different OSTs?

Hello,

  Is it possible to get sub-directories to inherit a non-default striping
configuration from their parent directory?  In other words, if I use lfs
setstripe to set the striping configuration for a given directory, can any
subdirectories created within that parent directory also have the same
striping configuration as the parent?

Thanks
 Sonja
