Hi Horst,

Thanks for the info.

AIX 5.2 problem is a different one. I still haven't tried writting any large file on AIX.
The problem is different on AIX: turning on the largefileserver compiler flag makes "vos dump" fail at server side because of a 64-bit type safety issue.
After fixing that issue, I have run into filesystem corruption, too.
So it's not a JFS or other limitation issue there.
See the ticket I've mentioned in the link in my prev. mail.

For Linux the problem is different.

I'm trusting our testers, so I still haven't checked these trivial conditions (they stated they have enough space at server side).
Now that I see it's not an experimental feature, I'm going deeper to check them.
