Is there a way of creating an ISO image bigger than 4Gb on Solaris?

mkisofs appears to have a 4Gb limit.

Sorry, I hit send too soon, I should have said mkisofs appears to have a
4Gb limit on the input file size.  I was attempting to run mkisofs on a
4.3Gb tar file.

within an ISO-9660 filesystem and this is actually part of
the ISO-9660 standard unless it has changed recently.
Of course, there is no limit on the iso image itself
only the files within the system.

I have personally never generated an iso image greater than
4.4 GB since I haven't started burning dual layer DVD's yet
but I would think that mkisofs should be able to handle
that in Solaris 10.

# mkisofs -o test.iso test.tar
mkisofs: Value too large for defined data type. File test.tar is too
large - ignoring
# ls -l test.tar
-rw-rw-r--   1 ian      staff    4544905728 Jul 23 14:07 test.tar

I'm assuming the 'defined data type' is a 32 bit unsigned int.

You could split it into 1G pieces. I frequently
need to move big images to file systems with 2G limit
and I use "split". You could do something like:

% mkdir data
% cd data
% split -b 1000m /path/to/test.tar
% cd ..
% mkisofs -o test.iso data

To recreate the original test.tar you can simply do
% cat xaa xab xac xab xac > test.tar
(The 1G pieces generated by split get named xaa xab ...)

Solaris hsfs currently has a 4 GB limit for single files.

This will change before the end of this year.

You will see Joliet support soon, followed by hard link support.

Supporting files > 4 GB needs a lot of changes (support for multi-extent
files).
