New OS

  • use the fill_swrep script to populate SWREP

Find scripts and config files in CB5/src/begrid/cb-client/cb-client-swrep to refill the repositories and create the templates.

mkdir tmpp
cd tmpp
wget http://quattor.begrid.be/begrid/install/newOS.tar.gz
tar xzf newOS.tar.gz
  • do

## link to comps.xml file

sed -i 's/PREF_ARCH/PREF_COMPAT_ARCH/' $PWD/rpms/get_compat_pkgarch.tpl
cd rpms
tar cvf ../all_$NEWOS.tar *tpl
  • copy the tarball all_$NEWOS.tar to your workspace and add them in the new repository under rpms/
  • edit the file get_pkgarch.tpl and add the line
include rpms/get_compat_pkgarch;
  • set the value for PREF_ARCH in get_pkgarch and PREF_COMPAT_ARCH in get_compat_arch
    • make sure they exist (esp look for differences in i686 and i386!!
  • on the centralised server, go to /var/www/html/begrid/install
  • make a new directory with name of OS in quattor
  • recreate the structure as from the mirror
    • make sure there is a direcotry called images with the correct images
    • make sure there's a symlink to the RPMS in /var/www/html/begrid/Central_BEGrid_Repository/
    • create the repomd.xml files
NEWOS=x86_64_cos5_51
cd /var/www/html/begrid/install/apt
./make_repos.sh $NEWOS
    • contos 5 required that the repodata directory was also present in the install base.
  • on the quattor client, create a new pxe directory
NEWOS=x86_64_cos5_51
## URL to images directory
PXEIMG=http://ftp.nluug.nl/ftp/pub/os/Linux/distr/CentOS/5.1/os/x86_64/images/pxeboot/
cd /osinstall/nbp
mkdir $NEWOS
cd $NEWOS
for i in vmlinuz initrd.img
