The kernel version is found with uname -r or cat /proc/version.<br class="">
<br class="">
That needs to match the kernel version in the Lustre RPMs. (The
version string is the 2.6.32-573.12.1.el6_lustre) part.<br class="">
<br class="">
In fact, it looks like you've got Lustre server RPMs, given the
_lustre in the name of the kernel. That means you need to install
the associated kernel.<br class="">

says to check dmesg... Though that will just list the
symbols. In general, this usually means you've got a
mismatch between the version of the kernel (or OFED)
Lustre is built against and your version of either the
kernel or OFED. Given the number and locations of the
mismatches, I'm guessing it's the kernel.<br class="">

So, compare your kernel version and your Lustre RPMs.<br class="">
