Hi there:
  I have a very critical problem with very large files. I have 3 SGI machines exporting a directory via NFS with >2G files. I need to mount this directories in a Linux Redhat 6.2 machine. Now I can't read this large files. What must I do? Where i can find the patches for the linux kernel? I also need to read from this files ussing C and i'm sure i can't do it with the standard libraries. Where I can find info about this? Please point me to the solution as soon as you can and I will give more points to the question.

Thanks in advance and sorry for my poor english.

xabi,
Need some clarification.
1. "Now I can't read this large files". So this mean you were sucessful in exporting and mounting the directories that contain these files?
2. "I can't read this large files".  Are you able to read smaller files using the same export/mount method?  Are the file formats compatable between the SGI and Linus file systems?
3. "Patches for the linux system".  You can search www.redhat.com or www.gnome.com  However, are you saying there is a patch that will fix your problem?
4. "read file using c".  I think you have a problem here. This might not be possible. What you really should do is contact http://dir.yahoo.com/Business_and_Economy/Business_to_Business/Computers/Hardware/Systems/Workstations/SGI/
and post this question in the USERNET.

To access "large files" (files larger than 2GB) you need to have a system that has "large file support" (LFS) compiled in kernel (2.4 kernels contain this) and in glibc. redhat 7.x already has this, but for rh 6.2 you may need to install a 2.4 kernel and a version of glibc compiled against 2.4 kernel headers (this provides LFS). Also, make sure to verify all the points mentioned in the above comment.
