Yet Another Beowulf Installation Howto

Beowulf Installation -- Kernel Upgrade

• download, unpack, configure and compile the new kernel in /usr/src/linux (you can use the configuration saved before). Do not forget to do make modules and make modules_install
• also add the hardware monitor module:

      # cd
      # cd lm_sensors-1.4.12/
      # make clean
      # make
      # make install
      # insmod /lib/modules/extra/misc/lm_sensors.o
      # cat /proc/sensors  
  

• Now, lets make new rpm.

  # cd /usr/src/redhat/SPECS
      # cp kernel-node.spec kernel-node.spec.old
      # vi kernel-node.spec
    ... change the kernel version, update script, etc ...  (xxx ... and explicaton here ... xxx)
      # rpm -ba kernel-node.spec 
  

  Now we have one poor man's rpm which is ready to be installed on the nodes. Cross your fingers and type (it is good idea to test the new rpm with one node before using 'bcomm' xxx ... to add more details here ... xxx):

      # bcomm "rpm -U ftp://sol/pub/linux-2.2.6-1.i386.rpm"
      # bcomm "shutdown -r now"
  

  Wait ... than check the result:

      # bcomm "uname -a"
