One more thought. I'm anxiously awaiting the outcome of a bet to see if rules for AIX 5.1 filesystems hold when you nfs mount a filesystem from a 5.1 server to a 4.3.3 server. We have this problem with exceeding a 64 gig file limit. 5.1 has a 1 TB file limit. Now the question is which server keeps track of the file and file transactions. ***Hums Jeapordy Theme*** there's a 10 dollar lunch at stake over this.
