Red Hat Bugzilla – Bug 132998
amd-64 dvd iso image too large to fit on a dvd
Last modified: 2007-11-30 17:10:49 EST
Description of problem:
AMD-64 dvd iso image of fedora core 3 test 2 (2.91) is
4.6GB in size while a blank dvd disk will only hold 4.4GB.
The i386 dvd iso image is rightly sized though.
Version-Release number of selected component (if applicable):

*** Bug 133452 has been marked as a duplicate of this bug. ***
Interestingly, I burnt the DVD image using overburn option (which
basically simply ignores that the image is larger than the disk and
writes as much as it can) and did a successful install using that. I
guess for this install, the installation program simply didn't call
for the packages that were not burnt on the disk...
The problem with 'overburn' mode is that it'll basically
ignore the fact that there really isn't enough space, and proceed
anyway. In this case serendipity may be on our side and the resultant
disc is installable, but one doesn't know what, if anything, actually
'gets lost' / corrupted without some extensive investigation.
For this reason (and general principle) I've commended placing MD5/SHA1
hashes on all discs as a standard process --
growisofs -overburn -Z /dev/sr1=../FC3-test2-x86_64-DVD.iso
About to execute 'builtin_dd if=../FC3-test2-x86_64-DVD.iso
of=/dev/sr1 obs=32k seek=0'
:-( /dev/sr1: not enough space available to accomodate this volume!
:-( /dev/sr1: 2295104 blocks are free, 2387426 to be written
4697325568/4700372992 (99.9%) @2.4x, remaining 0:00
:-[ LBA=230540h, SENSE KEY=5h/ASC=21h/ASCQ=00h ]
:-( write failed: Input/output error
So the image is exactly
189,075,456 bytes too large, which is much larger than is
possible by any account I'm aware of to possibly overburn on
a standard DVD+/-R/RW without data loss.
Looking at a directory of the files on the disc sorted by size,
I'd vote for leaving out the OpenOffice / Koffice / KDE SRPMs
which are quite large... and by the time anyone wants to hack
on office applications they probably have a pretty well functioning
system which can be used to download the SRPMs / CVS for those.
To check the integrity of your disc --
mount FC3-test2-x86_64-DVD.iso /media/loop0 -t iso9660 -o
(cd /media/loop0 ; find . -type f -print0 | xargs -0 md5sum --binary )
(cd /media/sr1 ; find . -type f -print0 | xargs -0 md5sum --binary ) >
Then a diff --minimal of
shows the following corrupted files -- fortunately none
of them seem needed for the basic install --

shell script to remaster FC3test2 X86_64 DVD .iso
I've created a script to take the .iso and remaster it without the OpenOffice
and koffice SRPMs. The resulting .iso works for me. I will attach the script.
Be sure to review it before running it. The initial definitions will need to
be adjusted for your environment.
FC3T3's x86_64 ISO is 2630025216 bytes. Appears that SRPMS were
removed. I believe this issue is solved.
Closing this out, as the DVD image is indeed small enough now to fit.
