k3b says "your mkisofs doesn't support large files"etc
When I burn a HDTV file(4.3GB) into a DVD, k3b says something like "your mkisofs doesn't support large files" etc.. So the burn failed. Even I have chosen UDF as the DVD file system. I noticed that the version of cdrtools in slackware is 2.01.01a53 but the last is 2.01.01a55. When I try to compile 2.01.01a55, Pat's SlackBuild scared me because it apply patches to the source and build zisofs-tools together. It may too hard for me to handle.
Can someone help me? Thanks in advance~~ |
There's some file size limit around 2 gigs, and it's a kernel thing.
A way around this might be to use growisofs, which does not write a temporary file, but builds the iso on the dvd, thus avoiding the handling of a large file. It will cost you one dvd to find out if it works :-). |
Thats curious since at least the 2.4 series file sizes were supported up to at least 4 GB. Perhaps it might depend on the FS itself though. I use JFS, so I have no issue with huge file sizes. Especially when I have 7-8GB iso files. (I use JFS)

Thanks for the reply ;)
I did a simple google search on file size limitations on different FS.[1][2][3] The summary is both Ext3(my local FS) and UDF(chosen as the DVD FS) could handle 4GB files. So the problem is not FS or kernel related. But I will try growisofs when I have spare time again ;) I think burning a iso image is different from burning files. Burning a iso don't need to build up the disk FS as everything is prepared. Oh, if you burn the iso FILE onto the disk, it will be my case ;) [1]:http://en.wikipedia.org/wiki/Ext3 [2]:http://en.wikipedia.org/wiki/Comparison_of_file_systems [3]:http://www.hydrogenaudio.org/forums/...hp/t24791.html |
You have the error "mkisofs can't support large file sizes>". Proceed in a logical fashiion, and eliminate things.
dd if=/dev/zero of=/tmp/myhugefile bs=1M count=4300 will write a huge file of about 4.3 gigs to disk. That will check out the hardware and space without involving mkisofs. If you then run mkisofs on it and that fails, you have your answer. |

In the "Burn" dialog, switch to the "Filesystem" page, press the "Custom" button in the "File System" tab, in the "File System Settings" tree, select "Level 3" for "ISO9660 Settings | ISO Level".

I noticed this error in a system that had been working fine in this mode. It turned out there was a corrupt (uncopiable) file which was causing this ("your mkisofs doesn't support large files").
