Preparation

Enable the Dag repo

rpm -Uhv \

http://apt.sw.be/redhat/el5/en/x86_64/rpmforge/RPMS//rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm

Enable the Epel repo

rpm -ivh http://download.fedora.redhat.com//pub/epel/5/`uname -i`/epel-release-`cut -d” ” /etc/redhat-release -f 3 |awk -F”.” ‘{print $1}’`-`cut -d” ” /etc/redhat-release -f 3 |awk -F”.” ‘{print $2}’`.noarch.rpm

Install the gcc and other tools

yum install -y make gcc gcc-c++ ncurses-devel.x86_64 automake autoconf boost-devel.x86_64 libedit-devel.x86_64 fuse-devel.x86_64 rpm-build.x86_64

Get the kernel source from kernel.org

http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.29.1.tar.bz2

Get the Ceph-0.8 sources package

from: http://ceph.newdream.net/download/

http://ceph.newdream.net/download/ceph-0.8.tar.gz

Proceed

mkdir build_cluster

cd build_cluster

tar xf linux-2.6.29.1.tar.bz2

tar xf ceph-0.8.tar.gz

cp -r ceph-0.8/src/kernel linux-2.6.29.1/fs/ceph

Edit the linux-2.6.29.1/fs/Kconfig file about line 269

—-here —- add the following line ——

source “fs/ceph/Kconfig”

—————————————————

it should looks like

(ignore….)

source “net/sunrpc/Kconfig”

source “fs/smbfs/Kconfig”

source “fs/ceph/Kconfig” #add for ceph

source “fs/cifs/Kconfig”

source “fs/ncpfs/Kconfig”

source “fs/coda/Kconfig”

(ignore…..)

Edit the linux-2.6.29.1/fs/Makefile file and the following line to the end of it.

—-here —- add the following line ——

obj-$(CONFIG_CEPH_FS) &nbsp ; += ceph/

—————————————————

make menuconfig

we should find the ceph modules in File Systems-> Network File Systems-> Ceph distributed file system (EXPERIMENTAL)

https://clearspace:8443/clearspace/servlet/JiveServlet/download/1217-1-1138/Picture%2036.png

we are compile a kernel for server, so there are some uneed modules, like sound, wireless, and others

the config we used here is the attachment

make rpm

we will get the new kernel

/usr/src/redhat/RPMS/x86_64/kernel-2.6.29.1vceph-3.x86_64.rpm

/usr/src/redhat/SRPMS/kernel-2.6.29.1vceph-3.src.rpm

rpm -ivh /usr/src/redhat/RPMS/x86_64/kernel-2.6.29.1vceph-3.x86_64.rpm

Next we need to generate the initrd for modules.

mkinitrd –without-dmraid /boot/initrd-2.6.29.1vceph 2.6.29.1vceph

edit the /etc/grub.conf add the following lines

—-here —- add the following line ——

title 2.6.29.1-Vcluster

root (hd0,0)

kernel /vmlinuz-2.6.29.1vceph ro root=/dev/VolGroup00/LogVol00

initrd /initrd-2.6.29.1vceph

—————————————————

my /etc/grub.conf looks like

—-here —- Start ——-

default=1

timeout=5

splashimage=(hd0,0)/grub/splash.xpm.gz

hiddenmenu

title CentOS (2.6.25)

root (hd0,0)

kernel /vmlinuz-2.6.25 ro root=/dev/VolGroup00/LogVol00

initrd /initrd-2.6.25.img

title 2.6.29.1-Vcluster

root (hd0,0)

kernel /vmlinuz-2.6.29.1vceph ro root=/dev/VolGroup00/LogVol00

initrd /initrd-2.6.29.1vceph

—-here —- End ——–

reboot
