so, if you install this kernel the kernel modules of
the rhcs and rhgfs will install but, in order of use
it, you will need to run that "old" kernel too :-(
so your computer will be at risk.

so, what I usually do is:
1- after instaling the kernels modules I will get an
extra directory inside the kernel module directory
(/lib/modules/<kernel version for which the gfs was
compiled>/extra)
2- move or copy that extra directory to the kernel
module directory of the new kernel:
/lib/modules/2.6.9-42.0.2/extra
3- run depmod command (if you are running the new
kernel the command will not need any argument, if not
...)

ok, that is a "hack" to get the system working with
the security-ok kernel but is not the right solution
(the new extra directory in the kernel module
directory and the files insight it, will be orfans,
they can't be uninstalled with rpm :-( ). the right
solucions should be recompile the cluster suit and the
GFS for the new kernel but ....
