 ocfs2-2.6.9-42.EL-1.2.4-2.i686.rpm 要求内核为 2.6.9-42.EL (找不到 2.6.9-42.ELsmp 的内核升级rpm所以只好找个EL的应付一下 )
 
 先在网上找到 kernel-2.6.9-42.EL.i686.rpm,mkinitrd-4.2.1.6-1.i386.rpm 这两个rpm，
 1、更新 mkinitrd
 删除 mkinitrd-4.1.18
 [root@guolinuxorcl1 oracle]# rpm -e --nodeps mkinitrd-4.1.18-2
 安装 mkinitrd-4.2.1.6
 
 [root@guolinuxorcl1 oracle]# rpm -ivh mkinitrd-4.2.1.6-1.i386.rpm
warning: mkinitrd-4.2.1.6-1.i386.rpm: V3 DSA signature: NOKEY, key ID 443e1821
Preparing...                ########################################### [100%]
   1:mkinitrd               ########################################### [100%]
  
 2、安装    kernel-2.6.9-42.EL 内核
 备份 /boot
 [root@guolinuxorcl1 ~]# cp -R /boot /boot.old
 [root@guolinuxorcl1 oracle]# rpm -ivh kernel-2.6.9-42.EL.i686.rpm
warning: kernel-2.6.9-42.EL.i686.rpm: V3 DSA signature: NOKEY, key ID a7048f8d
Preparing...                ########################################### [100%]
   1:kernel                 ########################################### [100%]
  
   3、编辑 grub.conf

[root@guolinuxorcl1 oracle]# cd /boot/grub  
  
   [root@guolinuxorcl1 grub]# vi grub.conf

# grub.conf generated by anaconda

# NOTICE:  You have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /boot/, eg.
#          root (hd0,0)
#          kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00
#          initrd /initrd-version.img
