[Pvfs2-users] Kernel Module - Compilation error

[Peng Gu]

I encountered a similar situation on my 4 pvfs2-server nodes.

All of the four nodes are equipped with a Intel Xeon, Fedora Core 5,
pvfs2-1.4.0.

At the very beginning, the kernel module won't make. Here are the errors I got.

# make kmod
  CC [M]  /usr/src/pvfs2-1.4.0/src/kernel/linux-2.6/inode.o
/usr/src/pvfs2-1.4.0/src/kernel/linux-2.6/inode.c: In function ?pvfs2_setattr?:
/usr/src/pvfs2-1.4.0/src/kernel/linux-2.6/inode.c:321: warning:

make[3]: *** [/usr/src/pvfs2-1.4.0/src/kernel/linux-2.6/inode.o] Error 1
make[2]: *** [_module_/usr/src/pvfs2-1.4.0/src/kernel/linux-2.6] Error 2
make[1]: *** [default] Error 2
make: *** [just_kmod] Error 2


Then I overwrite two files, namely "configure" and "configure.in"
(only these two files) from the official cvs tree. All the other files
are from pvfs2-1.4.0 tarball and are not touched.
The cvs command used to get the cvs tree was:
cvs -d :pserver:anonymous at cvs.parl.clemson.edu:/anoncvs co pvfs2

Now I am able to make, make install, make kmod, make kmod_install.
But I got new problem here: insmod complains:
# insmod usr/src/pvfs2/src/kernel/linux-2.6/pvfs2.ko
insmod: error inserting
'/usr/src/pvfs2/src/kernel/linux-2.6/pvfs2.ko': -1 Invalid module
format

Any ideas?

Thanks in advance,

Peng
