Re: Clustermatic with SCSI

   The kernel we were using was kernel-smp-2.6.5-1.358.x86_64
The error we found was
depmod: QM_MODULES: Function no implemented.
when trying to install the bproc modules. We have tried
to install several versions of module-init-tools but the
problem persists. Again, when trying to install the clutermatic
kernel over a system over a 2.6 kernel, we get complains
about the cm4 kernel being an older version. If we force
its installation with rpm --force, we get the cm4 kernel
to install, but the machine doesn't boot, probably because
the kernel does not recognizes the hard disks.
  Any suggestion is welcome.
  Leandro.
