Building an HP SFS client kit manuallyC–6

To create a built kernel tree, perform the following steps:

a. Extract the kernel sources from the src/ directory and put them in the build/linux/

directory, as shown in the following example:

$ mkdir -p build/linux

$ cd src/linux-2.4.21/

$ tar -cpf - ./ | (cd ../../build/linux; tar -xpf -;)

$ cd ../../

b. Apply the Lustre patches, as follows.

i. Extract the Lustre source files, as follows:

$ cd build

$ tar -xzpf ../src/lustre-V1.4.tgz

$ cd ..

ii. Apply the patches listed in the appropriate series file (under the build/lustre-

V1.4/lustre/kernel_patches/series/ directory) to the kernel tree, as follows:

$ for i in $(cat build/lustre-V1.4/lustre/kernel_patches/series/client-

rh-2.4.21-40); do cat

build/lustre-V1.4/lustre/kernel_patches/patches/"$i" | (cd build/linux;

patch -p1); done

c. If any patches are needed for the interconnect, apply them now. The following is an example of

applying the qsnet patches for a Quadrics interconnect:

$ tar -xjf src/qsnetpatches-RedHat-2.4.21-40.EL.qp2.0_hp.tar.bz2

$ cd qsnetpatches-RedHat-2.4.21-40.EL.qp2.0_hp/

$ tar -xjpf qsnetpatches.tar.bz2

$ cd ../

$ cat qsnetpatches-RedHat-2.4.21-40.EL.qp2.0_hp/qsnetpatches/*.patch | (cd

build/linux; patch -p1)

d. Apply the additional required patches to the kernel sources in the same way that you applied

the Lustre patches in Step b of this procedure. See Section 3.2.6 for an example list of additional

patches.

You can find the additional patches in the src directory; you can find the series file (which

lists the patches) in the /mnt/cdrom/client_enabler/src/arch/distro/patches/

directory.

The following is an example of the command that you would use to apply the patches:

$ for i in $(cat

/common/linux/kits/lustre/jimi_clients/current/SFS_V2_2_South_ce_cd/

client_enabler/src/x86_64/RHEL3.0_U7/patches/client_RHEL3_U7_series);

do cat src/"$i" | (cd build/linux; patch -p1); done

e. Regenerate the kernel config file.

• If it is necessary for your system requirements, modify the config file.

•If the config file does not require any customizations for your requirements, enter the

following commands:

$ cd build/linux

$ make oldconfig

$ cd ../../

NOTE: Note that if you are using an x86_64 or i686 system, you must configure the following

setting:

CONFIG_STACK_SIZE_16KB=y

f. Build the kernel and modules.

Depending on your client distribution and architecture, the command line varies. For example,

for i686 (ia32), ia32e (em64t), x86_64 architectures, the command is as follows:

$ make dep clean; make bzImage modules

For ia64 architectures, the command is as follows:

$ make dep clean; make compressed modules
