[Lustre-discuss] Lustre 1.8.2 patchless with RHEL5.5?

[Trent Johnson]

Until the weak modules support is added to the Oracle provided rpms, I 
am using the script in /etc/rc.modules with centos 5.5.  It will detect 
a new kernel without lustre modules installed at boot time, and create 
symlinks to the currently installed lustre-client-modules package.

#!/bin/bash
LVERSION=`rpm -ql lustre-client-modules | grep lib/modules |head -n 1 | 
cut -d "/" -f 4`
if [ ! -z $LVERSION ]; then
     if [ ! -d "/lib/modules/`uname -r`/kernel/fs/lustre" ]; then
         echo "Current kernel does not have lustre modules..."
         echo "Promoting modules from $LVERSION to `uname -r`"
         mount -o remount,rw /
         mkdir -p /lib/modules/`uname -r`/kernel/{fs,net}/lustre/
         ln -s /lib/modules/$LVERSION/kernel/fs/lustre/* 
/lib/modules/`uname -r`/kernel/fs/lustre/
         ln -s /lib/modules/$LVERSION/kernel/net/lustre/* 
/lib/modules/`uname -r`/kernel/net/lustre/
         depmod
         mount -o remount,ro /
     else
         echo "lustre-client-modules not installed"
     fi
     else
     echo "lustre-client-modules already installed in `uname -r`"
fi
