Actually, I though that too ... *BUT* there *IS* a patch to support
>2GB files on Ext2 partitions.  It is now part of the 2.3.x series.
 I too thought it was impossible until I saw it in the change logs.
 Maybe Ext2 *DOES* allow for 64-bit file sizes (but the
unpatched kernel only uses 32-bit values for computations)?!?!?!

Maybe it is just a patch to support upto 4GB files?  I don't know. 
That would support my 2.5GB file.  But once I upgraded to
2.2.14-12, I was stuck at the 2GB limit again.

Anyone know any more info???

And I know this isn't "proof" or anything, but here's that file on
an Ext2 partition (from when I was running 2.2.14-6.1.1):

rw-r-----   1 ryan     staff    2593838749 May 20 20:50 oldpcshares.tgz

Our attempt to re-copy it under 2.2.14-12 failed a second time.
