Re: [Moosefs-users] rack awareness

Thanks, Dr. Chudobiak.  I hadn't realized that man page existed.  It
does tell me what I need to know, which, unfortunately, as in Atom's
case is not what I was hoping for.  As someone mentioned in the backup
strategies thread, it would be great for backup if files were
distributed across all racks.  That is, indeed, exactly the use I had
in mind.
