AddingMachineToCluster

HOWTO: add a machine to the cluster

• This small tutorial will list the steps to add a machine to the cluster
• The example given here is a dcache headnode in the shadow cluster running on a virtual machine

Quattor

• In quattor following templates need to be adapted
  • /CBv6/cfg/clusters/iihe-glite-shadow/profiles/profile_dcache2-shadow.iihe.ac.be
  • Define type of machine
  • /CBv6/cfg/clusters/iihe-glite-shadow/private/dcache2-shadow.iihe.ac.be
  • Placeholders for the machine keys
  • /CBv6/cfg/sites/iihe-shadow/site/os_version_db.tpl
  • Define OS version to install on the machine

escape("dcache2-shadow.iihe.ac.be"),"sl550-x86_64",

• • /CBv6/cfg/sites/iihe-shadow/site/databases.tpl
  • Add an IP address for the machine:
  • Warning: Use nslookup and ping to see if this ip exists in the DNS and/if it is pingable

escape("dcache2-shadow.iihe.ac.be"),"193.190.YYY.XXX",
escape("dcache2-shadow.wn.iihe.ac.be"),"192.168.YYY.XXX",

• • Point the machine to the hardware

escape("dcache2-shadow.iihe.ac.be"),"hardware/machine/Virtual/virtual_kvm_dcache2-shadow",

• • /CBv6/cfg/sites/ulb-vub/hardware/machine/Virtual/virtual_kvm_argus.tpl
  • Change the name and add a unique MAC address (or the real MAC address in case of a physical machine)
• Then compile the templates in your local workspace
• If build successful, add/update the changes to the repository

Add the ip addresses of the machine to the DNS

• This should be done as explained here GridAdminSurvivalGuide#HowtoaddanewmachineintheDNS

Machine certificates

• This page explains howto request certificates for the machine UpdateCertificates
