Prerequisites

• This HOWTO will be the general OSR Howto in futur time. Until now it is still under CONSTRUCTION. So please be patient.
• See assumptions

Install Com.oonics packages

Install the latest comoonics packages from a comoonics yum channel.

Create a cluster configuration file

Download the apropriate cluster configuration from cluster configurations

Create the shared root filesystem

1. See mountnfs
2. Copy all data from the local installed RHEL5 root filesystem to the shared root filesystem

cp -ax / /mnt/newroot/

3. Create some directories if need be

mkdir /mnt/newroot/proc
mkdir /mnt/newroot/sys

4. Create a new cdsl infrastructure on the shared root filesystem

com-mkcdslinfrastructure -r /mnt/newroot

5. Mount the local cdsl infrastructure

mount --bind /mnt/newroot/.cluster/cdsl/1/ /mnt/newroot/.cdsl.local/

6. Mount other deps to be able to chroot

mount --bind /mnt/newroot/proc /mnt/newroot/proc
mount --bind /mnt/newroot/sys /mnt/newroot/sys
mount --bind /mnt/newroot/dev /mnt/newroot/dev
chroot /mnt/newroot

7. Make '/var' subdirs hostdependent

com-mkcdsl -a -f /var/tmp/
com-mkcdsl -a -f /var/account 
com-mkcdsl -a -f /var/cache 
com-mkcdsl -a -f /var/local 
com-mkcdsl -a -f /var/lock 
com-mkcdsl -a -f /var/log 
com-mkcdsl -a -f /var/spool 
com-mkcdsl -a -f /var/run
com-mkcdsl -a -f /var/lib/dbus 
com-mkcdsl -a -f /var/lib/dhclient

8. Have a look at /var/run problems with multipathd: multipathdbug
9. Make '/etc/sysconfig/network' hostdependent

com-mkcdsl -a /etc/sysconfig/network

10. Exit from the chroot

Create boot configuration

1. Create the boot "filesystem" see createboot
2. Create Shared Root initrd

Create the shared root initrd into the shared boot filesystem

chroot /mnt/newroot /opt/atix/comoonics-bootimage/mkinitrd -f /boot/initrd_sr-$(uname -r).img $(uname -r)

Afterworks

For afterworks see afterworks.

Clean up

On installnode exist the chroot and

umount /mnt/newroot/cdsl.local

umount /mnt/newroot/dev

umount /mnt/newroot/proc

umount /mnt/newroot/sys

umount /mnt/newroot

Boot Cluster

Have Fun !!
