[gentoo-user] how to make large iso with mkisofs?

[David Shen]

Hi,

I have a blue-ray dvd copied on disk, it is about 20GB large, when I
use mkisofs, it reports my files are too large. Is there any way to
fix this?

I don't have a Blu-ray drive and never used one, but you can try to
use growisofs from app-cdr/dvd+rw-tools. It contains examples in the
manpage:

To master and burn an ISO9660 volume with Joliet and Rock-Ridge
extensions on a DVD or Blu-ray Disc:

growisofs -Z /dev/dvd -R -J /some/files

To append more data to same media:

growisofs -M /dev/dvd -R -J /more/files

Make sure to use the same options for both initial burning and
when appending data.

To finalize the multisession DVD maintaining maximum compatibility:

growisofs -M /dev/dvd=/dev/zero

thanks, but I have just found an easier solution, just add -iso-level
3 to mkisofs option. the iso level 3 do not have restriction on file
size.

If your problem has been that you need multi-extent files for your purpose, you
are correct.

growisofs only handles writing the data to the disc,the rest of the work
it hands over to mkisofs.

Which files are "too large"?
Are you using mkisofs?
