I thought this had been resolved in a previous append. Without  
examining the code of tar I cannot be sure but this smacks of a  
coding defect. My guess is that you have TOO MUCH free space. Why?  
Because tar is checking the available free-space but (probably)  
storing it in a too small value (e.g., short instead of int or int  
instead of long long) therefore overflow occurs and the resulting  
value indicates insufficient free-space even though that is not true.

You can prove this by creating dummy objects to consume lots of free  
space. Something like:
	CRTPF DUMMY/DUMMY00001 RCDLEN(32767) SIZE(2147483647) ALLOCATE(*YES)

repeated until sufficient space is consumed.

This sort of rubbish happened a lot in the early days of DOS and Unix  
as drive sizes increased. I thought we were past that by now.
