Which filesystem are you using now? Ext3 obviously supports files larger than 2GB. Which version of mkisofs do you have? If that's what k3b uses to create ISO images, then mkisofs must be new enough (2.01 and above).

still using ext3, i want to test reiser on another system first before making changes to the fileserver

well, rpm -qa gives me:
mkisofs-2.0-6

single files >2GB are skipped whenever i try to burn...

That's because mkisofs 2.0 does not support files larger than 2GB. Like I said, you need to get version 2.01.

Exactly! Its an architeture issue. The kernel has some code to fool itself into going beyond the 32 bit imposed limits, but many apps haven't been coded to take advantage of that. mkisofs seems to have been one of them, fixed as of 2.01, as daihard has mentioned. Update your tool and you should be fine.

Sorry, thought you missed a "-" between 0 and 1 (2.0-1)
Thanks! I'll go download the file and update now!

# Which would you recommend? build from source or an rpm?
# I'm not that familiar with sources, i just know ./configure && make && make install...

I try to make an RPM from the source whenever possible. RPMs make it easier for you to keep track of the files you've got on your computer (e.g. preventing conflicts, etc). When I have to do manual "configure, make, make install," I make sure I set the prefix to /usr/local so it will not accidentally overwrite anything the system has installed.

Well, I tried making am RPM from samba's source since it has a makerpms script included, not sure about others though, is it the same process?
I might as well just google for more info

Now that's the part I always get confuse with! --prefix=??
I tried building gnome-2.8 from source and had my whole system messed up
Main reason is i only know ./configure, didn't set the prefix, so some sources were installed into /usr but some into /usr/local... well, point taken! Everything into /usr/local for safety!

Hi Daihard,
I tried out the alpha version, but even that version is unable to create an iso of file size 2 GB.

I wanted to know how do I write iso created using -split-output.

Please give us examples if you have done i, about how to write to a DVD using the splitted iso's.

Thnaks for your help,
Haoscar.

That's weird. To clear things up a little, the previous version of mkisofs that I had (2.0) was able to create an ISO image of larger than 2GB. It just wasn't capable of handling an original file larger than 2 GB. The alpha version (2.01-a38) has fixed that problem for me. I don't undestand why that isn't the case for you.

My English isn't that good... so you are saying:
Version 2.0:
(1) can make an iso image of a few files added up to be >2GB?
(2) but not make an iso of a single >2GB file?

Version 2.01:
fixes problem (2)?

Exactly.

I don't think your English is a problem at all.

Ah...got it!
I'll give 2.01 a try once i patch up a few grub problems (also cups, samba, reiserfs, chinese characters on terminal, raid... i wonder if this list will go on...)

Cheers, daihard

i did everything as suggested by you.

/opt/schilly/bin/mkisofs -r -o image.iso /home/user.

The iso got created of size 2.6 GB, but when I mounted it the .tar file inside it was only 16 MB.

to install I did

cd cdrtools-2.01

#]./Gmake.linux

#]./Gmake.linux install

Did I miss anything.
The tar ball I have is of 2.6 GB.

Does anyone know how to create a dvd out of iso created using -split-output option in mkisofs.

3 iso's got created. I dont know how to write all of them together on the dvd or even dummy mounting them together on a directory?

Daihard, do you know anything about this.

Thanks,
haoscar

There seems to be a lot of misinformation here. First, there is no problem with having very large files on Linux using ext3. I have many large files (> 30 gb). These files are hdtv recordings from digital OTA broadcasts. The limitation of 32-bit cpus has to do with memory addressing, not file size. (There are other things that could restrict file size but cpu memory addressing isn't one of them AFAIK.)

I have run into a problem recording files to DVD. I tried burning ~4.2 GB files (this is one single file - not an iso image) to DVDs using growisofs and K3B (which uses growisofs). I'm using a 32-bit version of FC2 (2.6 kernel) running on an Athlon 64 based system. (I had problems with drivers for my hdtv tuner when I was using the 64-bit version of FC2.) Each time I tried to burn the DVD using either growisofs directly or K3B I would get no errors. K3B reported success. But when I would mount the DVD, no more than about 7mb would be on the DVD. I also tried making a 4.2 gb iso image first using mkisofs. It seemed to make a good image (it was the correct size but I did not take the time to try to mount it - I should have). Same result when I burned it - only 7 mb was recorded. I posted this problem on some newsgroups. One person said he thought there was either 1 gb or a 2 gb limit on individual files in iso image file systems. When I split the file into pieces slightly bigger than 1 gb, I could get the files burned to the DVD.

You may be able to burn 4.7 or even larger iso images to DVDs (I would think at least 4.7 gb would be possible) so long as no single file exceeds 1 gb (or maybe 2 gb).

I'm using mkisofs 2.01 on FC2 and it will NOT let me burn an iso image to DVD if any single file is over 1.1 gb. (The actual limit may be 2 gb on a single file - haven't tried files that large yet. growisofs will not burn a 4.2 iso image where one file is 4.2 gb.) Maybe there is a way around this limitation but I have not found it.
