[Lustre-devel] ldiskfs build problem with rhel5.5

[Lustre-devel] ldiskfs build problem with rhel5.5

[Jay Lan]

Hi,

I ran into a problem in building ldiskfs-3.1.4 with 2.6.18-194.3.1.el5 
kernel.
The kernel was patched with kernel patches provided by lustre-1.8.5 and
ldiskfs-3.1.4.

The problem I encountered was that the kernel and kernel-devel rpms
did not provide fs/ext4/*.[ch], which the build process would need.

Is there a kernel patch for this problem?

Regards,
Jay

You shouldn't apply the ldiskfs patches to the kernel at all. They are applied to a copy if the ext3/4 sources during the Lustre build process. 

Cheers, Andreas

Does it deal with export_decode_fh ? Do you build againt OFED 1.5.2 ? If 
that is the case then I ran into that issue last week. OFED alters your 
kernel to build the modules but it doesn't alter the source tree. When  
lustre builds it looks at your source tree which is different then what 
the biniaries export. The solution is to copy what is in include-nfs/linux 
from OFED to your kernel source tree include/linux directory.

[Lustre-devel] Compiling source code

Hey 


I am new to lustre  and was trying to compile the lustre kernel and while giving a make i get the following errors.
Uncaught exception from user code:

make[2]: *** [lustre_build_version] Error 2

Hi Andreas,

No matter if I applied ldiskfs patches to the kernel or not, the
/isr/src/kernels/2.6.18-194.3.1.el5.<variant>-x86_64/fs/ext4
contains only Kconfig and Makefile. None of the .c or .h files
were there. But building ldiskfs would try to apply patches
to files in that directory which were not present.

Which rpm provides you those files in your rhel5.5
build environment?

Thanks,
Jay

Hi James,

I was building against ofed 1.5.2, but I did not run into the
problem you described though. But thanks for sharing your
solution.

Thanks,
Jay
