[ Software links provided within have been tested for LiveCD and CentOS build environments CentOS 6.5 and CentOS 6.4]
For those who have an existing Live CD build Environment, tools, and kickstart config file for LiveCD on an existing CentOS/RHEL.
- Go the following page and grab the zip file:
SWRAIDFILES.zip
When unzipped, it is already indexed as a CentOS repository that contains the
megasr driver RPM and the storcli software RPM – it also contains a
boot script makeswraidmirror that will be integrated into the LiveCD
to make the LSI software RAID1 device
In your build environment:
- mkdir /root/SWRAID
- move/copy the downloaded zip file to /root/SWRAID
- unzip the zip file
If you want to use a different directory to hold the zip contents, just change the
references to /root/SWRAID in the config file modification instructions below.
2. Examine the makeswraidmirror file. You will note that it proves
output to /dev/console ---- it was developed for use in a LiveCD
environment that boots WITHOUT a graphical login screen, so it
just provides output to the text console.
If you have a graphical environment booted on LiveCD, you might want
to change the output of the script and
redirect it somewhere else, or make other modifications
OR: you could modify your environment to be non-graphical.
(In intro section of the kickstart config file, change
any xconfig options to the single line skipx
3. Add repo to the kickstart config file
In the intro section, add the following line to point to the new software (it is already in repo format) – Note that has 3 consecutive slashes in the URL (two for the URL syntax, last one is part of the pathname).
repo --name=megasr --baseurl=file:///root/SWRAID
4. Add packages to the kickstart config file:
In the %packages section, add the following two package names at the end of the list:
kmod-megasr
storcli
5. Modify post-create script in the regular %post section (this runs in a chroot
environment in the LiveOSimage being built).
At the end of the section, add these lines (just cut and paste from here – only possible
variable is that directory /root/SWRAID if you put that stuff elsewhere.
echo "blacklist ahci" >>/etc/modprobe.d/blacklist.conf
cat >/etc/rc.local << EOF_rclocal
#!/bin/bash
service atd start
sleep 3
if dmidecode | grep -A 3 'System Information'| grep UCSC-C >/dev/null
then
at now + 1 min << EOF_ATT
/root/SWRAID/makeswraidmirror
EOF_ATT
fi
EOF_rclocal
6. Modify the non-chroot post-create section %post –nochroot (or create such a section
if you don’t have one yet)
Add the following lines at the end (just cut and paste from this document. The only variable
is going to be that directory /root/SWRAID, if you used something different:
cp -r /root/SWRAID $INSTALL_ROOT/root
rm -rf /var/tmp/initrd
mkdir /var/tmp/initrd
cp $LIVE_ROOT/isolinux/initrd0.img /var/tmp/initrd/initrd.gz
cd /var/tmp/initrd
zcat initrd.gz | cpio -ivmud
echo "blacklist ahci" >>etc/modprobe.d/blacklist.conf
rm -f initrd.gz
find . |cpio -ocv |gzip -9 >initrd0.img
cp -f initrd0.img $LIVE_ROOT/isolinux/
7. You are ready to use livecd-creator with your modified kickstart config file to create your new LiveCD image.
