1. LCG/EGEE Installation J. A. Templon Undecided (NIKHEF)
NROC Meeting, Amsterdam, 28 October 2004
LCG/EGEE Installation J. A. Templon Undecided (NIKHEF)
EGEE is a project funded by the European Union under contract IST

2. Contents The Installation Problem The Current Solution (LCFGng)
(LCFGng)ng == Quattor
How to proceed
NROC Meeting, 28 October

3. The Installation Problem
Installation of large numbers of nodes
Configuration of large numbers of nodes
Interchangeability of node functions (or even identities)
Configuration management
Allow for site customizations
NROC Meeting, 28 October

4. Config & Install Server

5. Current Solution: LCFGng
Configuration is a CPP macro
#define HOSTNAME node16-32
#define SITE_LOCALDOMAIN farmnet.nikhef.nl
#include "local/site-config-lcgprod.h"
#include "local/nikhef-sys-core.h"
#include "local/nikhef-sys-hw-amdncf.h"
#include "local/nikhef-sys-disk-generic.h"
#include "local/nikhef-fs-autofs.h"
#include "local/nikhef-auth-lusers.h"
#include "lcgprod/WorkerNode-cfg.h"
#include "local/nikhef-postconfig-lcgprod.h"
#ifdef SYS_LMSENSORS_SUPPORT

7. Sequence of LCFGng Node boots under dhcp -> hostname + profile
Bootstraps enough to get ‘rpm’ object (deals with RPMs) and installs rpm list
Reboots and does configs
Config changes are applied when profile changes
NROC Meeting, 28 October

8. Assessment Installation of large numbers of nodes
Configuration of large numbers of nodes
Interchangeability of node functions (or even identities)
Configuration management
Allow for site customizations
NROC Meeting, 28 October

9. Quattor Structured Configuration Database
Structured Software Repository
Management Tools for Each
Configuration “components” for various functionality
Compiler for configuration profiles (handles dependencies)
Automatic Install System integrated with dhcp
NROC Meeting, 28 October

14. How to Proceed LCG-2 profiles for Quattor exist (C. Loomis)
Quattor support materializing in GDB
Community action to develop, share, and support tools
NIKHEF is developing Quattor install for two systems (P4 Cert TB of VL-E and EGEE PPS)
