inode allocation and volume groups

[PAulN <pauln@xxxxxxx>]

Hi,
I know this the linux list but I have an irix question..
I was wondering if someone could please explain the policy for inode 
allocation
in an XVM environment.  To maximize performance,  I'd like to create a 
scheme where
multiple file creates in the same directory are distributed across 
volume groups.   If necessary,
I can resort to  creating the inodes in separate directories and 
hardlinking them  into the "proper"
namespace but it would be helpful to know what XFS is doing under the hood.

I've tried various tests to charaterize the behavior but still have yet 
to fully understand
how it works.  Could someone enlighten me?

Thanks,
Paul
