BuildingCentOSXfsKernelModules

The XFS Kernel Module for CentOS installation

The XFS kernel module (kmod-xfs) form the CentOS PLUS repository may sometimes be missing -- the plus part sometimes does not get built or is built later. We then have to build it ourselves like described below.

Please replace 78.0.8.EL with the actual kernel version you want, and build on a host with the proper architecture (although not necessarily the actual kernel version you're building towards).

x86_64

rpm -i http://stal.nikhef.nl/centos/4.7/updates/x86_64/RPMS/kernel{-,-largesmp-,-xenU-,-smp-}devel-2.6.9-78.0.8.EL.x86_64.rpm
rpm -i http://spiegel.nikhef.nl/mirror/centos/4.7/extras/SRPMS/xfs-kmod-0.4-1.el4.2.6.9_55.EL.src.rpm

and then

cd  /usr/src/redhat/SPECS/
rpmbuild -ba --define 'kvariants ""' --define 'kversion 2.6.9-78.0.8.EL' --target=x86_64 kmod-xfs.spec
rpmbuild -ba --define 'kvariants "smp"' --define 'kversion 2.6.9-78.0.8.EL' --target=x86_64 kmod-xfs.spec
rpmbuild -ba --define 'kvariants "xenU"' --define 'kversion 2.6.9-78.0.8.EL' --target=x86_64 kmod-xfs.spec
rpmbuild -ba --define 'kvariants "largesmp"' --define 'kversion 2.6.9-78.0.8.EL' --target=x86_64 kmod-xfs.spec

and copy over to the repository:

scp -p  /usr/src/redhat/RPMS/x86_64/*xfs*78.0.8*rpm ndpfmgr@stal:/project/quattor/www/html/mirror/nikhef/

or in reverse from stal:

scp -p root@hooikoorts:/usr/src/redhat/RPMS/i686/\*xfs\*78.0.8\*rpm .

i686

rpm -i http://stal.nikhef.nl/centos/4.7/updates/i386/RPMS/kernel{-,-hugemem-,-xenU-,-smp-}devel-2.6.9-78.0.8.EL.i686.rpm
rpm -i http://spiegel.nikhef.nl/mirror/centos/4.7/extras/SRPMS/xfs-kmod-0.4-1.el4.2.6.9_55.EL.src.rpm

and then

cd  /usr/src/redhat/SPECS/
rpmbuild -ba --define 'kvariants ""' --define 'kversion 2.6.9-78.0.8.EL' --target=i686 kmod-xfs.spec
rpmbuild -ba --define 'kvariants "smp"' --define 'kversion 2.6.9-78.0.8.EL' --target=i686 kmod-xfs.spec
rpmbuild -ba --define 'kvariants "hugemem"' --define 'kversion 2.6.9-78.0.8.EL' --target=i686 kmod-xfs.spec
rpmbuild -ba --define 'kvariants "xenU"' --define 'kversion 2.6.9-78.0.8.EL' --target=i686 kmod-xfs.spec

and copy over to the repository:

scp -p /usr/src/redhat/RPMS/i686/*xfs*78.0.8*rpm ndpfmgr@stal:/project/quattor/www/html/mirror/nikhef/

or in reverse from stal:

scp -p root@hooikist:/usr/src/redhat/RPMS/i686/\*xfs\*78.0.8\*rpm .

The mvSatalinux kernel module for the Thumpers

The Thumpers require the mvSatalinux kernel module. We have to build this module ourselves (x86_64 only!).

cd  /usr/src/redhat/SPECS/

Then edit the file mvSatalinux_3.6.3_2.spec and adjust the definition of kernel_type to match the new kernel, e.g.:

%define kernel_type 78.0.13.EL

Then build the rpm and copy it to the software repository:

rpmbuild -ba mvSatalinux_3.6.3_2.spec
scp ../RPMS/x86_64/mvSatalinux-2.6.9-78.0.13.ELsmp-3.6.3_2-1ndpf2.x86_64.rpm ndpfmgr@stal:www/html/mirror/nikhef/
