1. Repositories upgrade
? Upgrade your local RPM repository from
datagrid.in2p3.fr/distribution.
? A script was done by Steve Traylen to simplify the
download process:
– http://www.gridpp.ac.uk/tb-support/lcfgextra/createRepository.sh.txt
– http://www.gridpp.ac.uk/tb-support/lcfg-extra/Makefilegenheaders.txt
? I did not try it but it seems nice.

2. LCFG server upgrade
? Some rpms need to be updated/installed also in the LCFG
server:
– cd /opt/local/linux/6.2/RPMS/LCFG
– rpm -Uvh config-defaults-rpmcfg-server -1.0.022.edg.i386.rpm
– rpm -Uvh obj-filecopy-server-1.0-7.edg.i386.rpm
– rpm -Uvh obj-inet-server -1.0-0.6.edg.i386.rpm
– rpm -Uvh obj-nfs-server -1.0-0.9.edg.i386.rpm
– rpm -Uvh obj-nsswitch -server -1.0-0.4.edg.i386.rpm
– rpm -Uvh obj-update-server -1.0-18.edg.i386.rpm
– rpm -Uvh obj-xntpd-server-1.0-2.edg.i386.rpm

4. Download latest RPM lists

? Download latest LCFG RPM lists and put them into:
/opt/local/linux/6.2/rpmcfg

5. Download latest LCFG
resources
? From:
– http://datagrid.in2p3.fr/cgi -bin/cvsweb.cgi/edg-release/source/
? Download latest LCFG resource files and put them into:
– /var/obj/conf/profile/source

6. Customize your resources
? In theory only site-cfg.h

7. Update the testbed nodes
? Rebuild and notify the configuration changes with:
– touch /var/obj/conf/profile/source/linuxdef-cfg.h
– /usr/sbin/mkxprof -n -A -R
? The first command is a workaround to a LCFG adaptors bug
(Bugzilla #317).

8. Reboot
? Reboot to ensure that
– RPM are updated
– Upgraded demons are restarted

9. New boot disk
? A new boot disk was created to solve the problem of BOOTP
protocol (now we use DHCP) and to add the support for Realtek
Ethernet card.
? After the update of installroot you MUST use this disk image
instead of the previous one:
– http://www.lnl.infn.it/datagrid/wp4install/packages/disk_images/boot_nfs_25032002.img
? The problem of the length of the pathname (e.g. short link to
/opt/local/linux/6.2/installroot) and the URL of the LCFG server
was solved

10. "lcfgize-me"
? New tool: it is possible to install from scratch a node also without
the boot diskette
? But the node must be:
– Already up and running
– Configured with the lilo bootloader
? The tool lcfgize-me:
– Copy existing lilo.conf to a temporary location
– Add the new kernel
– Run lilo using this temporary configuration
? The new kernel will be the default image for the next boot; it will
mount the installroot via NFS and start the standard LCFG
installation process
? It is possible to "undo" (the /etc/lilo.conf is not modified)
? The installation is non interactive
