Hi,
There is .bz2 file about 3.5 GB and I am trying to create and iso using the
same.
The basic objective is to write the .bz2 file on the dvd disc.
When I try with -J option , I get the following error :
# mkisofs -allow-multidot -v -allow-lowercase -J -o /root/bin/sh/backup.iso
/backup/backup-2005May23.tar.bz2
Warning: creating filesystem that does not conform to ISO-9660.
Warning: creating filesystem with (nonstandard) Joliet extensions
but without (standard) Rock Ridge extensions.
It is highly recommended to add Rock Ridge
mkisofs 2.0 (i686-pc-linux-gnu)
mkisofs: Value too large for defined data type. File
/backup/backup-2005May23.tar.bz2
is too large - ignoring
Writing: Initial Padbock Start Block 0
Done with: Initial Padbock Block(s) 16
......................
....
Now when I try with the -R option I get :
# mkisofs -allow-multidot -v -allow-lowercase -R -o root/bin/sh/backup.iso
/backup/backup-2005May23.tar.bz2
Warning: creating filesystem that does not conform to ISO-9660.
mkisofs 2.0 (i686-pc-linux-gnu)

Writing: Primary Volume Descriptor Start Block 16
Done with: Primary Volume Descriptor Block(s) 1
............................................ .. ... .
1) Kindly let me know how can I create an iso file of that .bz2 file ? or
Alternatively how can I write a 3.5 GB on a dvd ?
Kindly help.
Regards,
Vijay Kumar

That won't work because the CDRecord family (including DVDRecord) only
understand certain ISO9660 track formats -- Red Book (audio), Yellow Book
(data, aka "ISO [data] file"), etc... Some versions support UDF
filesystems,
among others.
Now there _are_ some ways to write "raw" bits to CD/DVD devices.
But it's not recommend you do this because you can run into all sorts
of issues (e.g., endian/byte order differences between systems, etc...).
ISO9660 is a standard that nearly all systems adhere too.

Yes, you need to pre-master a file that the CDRecord family can understand
and record.

Mkisofs is the most common program for pre-mastering a file.
The mkisofs+cdrecord family of tools are assuming you want to pre-master
a file, and linearly record that file to a CD/DVD. If you have a
re-writable
media -- e.g., CD-RW, DVD-RAM, DVD-RW, DVD+RW, you typically don't
want (let alone don't need) to use this approach.
You should be able to rewrite the file directly to a pre-formatted,
rewritable
optical media using the direct device under Linux just like it was a ROM,
only writable as well. The way you do this varies based on program/access.
Growisofs is popular if you want to make an ISO9660 Yellow Book track
CD/DVD, which is the most compatible filesystem for CD/DVD. UDF is
another, popular format that is a superset of ISO9660, and comes as
the standard format for DVD-RAM discs, but is not as proliferated as
ISO9660 (i.e., many older Windows versions do not even include read-only
drivers, and most require 3rd party software to re-write UDF).
