[PVFS-users] errors when run the program put on pvfs

[Rob Ross]

We don't actively support executing programs off PVFS file systems.  It
works for some people, and not others.  Sorry it isn't working for you,
but this isn't the primary purpose of PVFS, we've spent a fair amount of
time trying to make this work without total success, and we can't justify
more time expended on this problem.

We are spending extra effort to make sure that this will work in PVFS2.

Regards,

Rob
