[lustre-devel] CentOS 6 - Build problems with kmod

[Christopher J. Morrone]

Yes, those instructions should be taken with a huge grain of salt.  For
instance, instructions for compiling lustre should really employ a
custom user and talk about "useradd" and such.  Also, most users can
skip the whole custom-patched-kernel section.  Hopefully all developers
will be able to stop that too by the time 2.9.0 comes out.

The error you are seeing almost certainly means that you don't have a
kernel installed that offers symbols compatible with the kernel that
lustre was compiled against.

It sounds like you built your own kernel.  Did you install all the
resulting kernel packages before building lustre (including any
devel-related packages)?  Is your custom kernel the newest kernel
installed on your system?
