Minutes Feb 22


Nate installed c001

Suchandra has been working on koan rules for the ITB
  • rules changed to use paravirtualized disk (libIO) and network

Plan for the week

Suchandra will send a request to ITS to allocate the Grid Colombia IPs to the new names

Suchandra will describe Puppet and Cobbler used in the ITB
  • ITB cluster puppet/cobbler narrative
  • high level, nothing long, something put together in few hours
  • not at the level of detail of the single rules
  • to document how to manage a small cluster

Next week all the worker nodes will be up:
  • 2 physical WN
  • one machine with KVM and 2 virtual WN

Marco takes a shot in rationalizing the node matrix:
  • Rationalized node matrix (situation as it is)
  • Node allocation describing the planning
Suchandra and Nate will check the tables

Suchandra: within 2 weeks Tier 3 machines will be decommissioned

ITB home directories:
  • problems with ITB home directories causing load
  • Tier 3 home dirs are being moved from edge4 (dying machine) to s1 (brand new server)
  • currently there are about 20 accounts, coming from LDAP
  • ideally Tier 3 and ITB should be decoupled from LDAP

Nate: get a rack mounted UPS for the critical Tier 3 machines
