growisofs newbie questions

[Helmut Jarausch <jarausch@igpm.rwth-aachen.de>]

Hi,

I have used growisofs for the first time and ran into some problems.

I tried to dump an ext3 file system using flyisofs (from shunt-1.6.3)
and growisofs like
/sbin/dump -y -b64 -0 -f - / | flyisofs mbc=2295104 fbc=350000 \
                             | growisofs -speed=4 -Z /dev/hdd=/dev/zero

dump reports "estimated 3010054 blocks' which means well below 3 Gb

flyisofs creates an iso-9660 file system of 229510482048 = 4700372992
bytes

dvd+rw-mediainfo /dev/hdd   reports
 Legacy lead-out at:    2297888*2KB=4706074624
 Track Size:            2297888*2KB

and growisofs starts with
         0/4706074624 ( 0.0%) @0x, remaining ??:??

and stopped with
4703748096/4706074624 (100.0%) @3.9x, remaining 0:00
:-[ WRITE@LBA=231020h failed with SK=5h/ASC=21h/ACQ=00h]: No space left on device
builtin_dd: 2297888*2KB out @ average 3.5x1385KBps


Why is it trying to write 4706074624 bytes, and why does it fail
if track size = 2297888*2KB=4706074624  ?

It's a Verbatim DVD-R medium.

And what can I do about it?

Many thanks for a hint,
