[Pvfs2-users] Problem mounting iso files saved on PVFS2

[Mark Van De Vyver]

Hi Murali,
Thank you for responding.  Please bear with me for a moment -  I'm
very green when it comes to linux, let alone pvfs2... having left the
win xp world 3 months ago :)

I used a Rocks Roll to setup PVFS2, so much of the configuration was
done behind the scenes.  Is this option to be set in a config file?  I
searched http://www.pvfs.org/pvfs2-options.html
but found no mention.

Thanks in advance
Regards
Mark
