Actions Completed

gLite support

• Fix permission/owner for BDII configuration file

Miscellaneous

• Decide location/date of next Quattor workshop (Budapest?)
  • Budapest agreed (Gabor, Oct. 27)
  • ​Doodle poll started to find appropriate dates: 20-22/3 chosen

Actions in progress

Documentation

• Initial Aquilon documentation
  • Usage
  • Installation (appliance)
• Document for component developpers best practices regarding logging and expected default verbosity

Build tools

• Use of new build tools for 1 or 2 NCM components (to be defined)
  • First require fixing schema

Configuration Modules

• ncm-network rewrite: validate initial rewrite (code review, deployment on a test system keeping in mind features not yet reimplemented)
  • See discussion during Strasbourg workshop
  • 8/12: work in progress for ip-route implementation. Not an easy task.
• ncm-dpmlfc: rewrite without dabase-related functions and use ncm-mysql to configure the database (changes required in DPM/LFC templates)
  • Direct mysql management removed, updating templates to use ncm-mysql
• ncm-gip2 should use perl-CAF to execute commands rather than `$cmd`
• ncm-ncd : implement dependency alias names to enable transparent replacement of a component by another one (or implement metadependencies)
  • User story: be able to say that spma dependency is in fact provided by ncm-yum.
• A few mods by Gabor waiting to be committed: ncm-network, ncm-blockdevices, 2 new AII hooks (Krb keytab saving before reinstall, postinstall templates)

AII

• Fix remaining AII issues for proper RHEL6 support
• Allow to use standard Anaconda disk formatting features rather than %pre script
• aii-pxelinux: use the MAC address instead of the interface name

Package Deployment

• SPMA replacement by YUM: from ​CERN experience, establish a list of possible development steps

QWG

• Implement OS namespace improvement (Michel)
  • vendor/version-arch or vendor/version/arch for OS templates
• Update CAF/LC to last versions (Michel)
• Agree on Pan annotation tags
• KVM support outside StratusLab (Jérome)
  • Discuss with Cal what can be reused in configuration modules developped by StratusLab
• StratusLab templates: do a code review and ensure they allow to start a site from scratch (Guillaume)
  • Several sites (RAL, Strasbourg) reported problems with distributed templates
  • Tbd with StratusLab team
• On RHEL/SL 6, ensure that kernel option nokz=off is defined by default in Grub configuration (significant performance impact)
• Prepare a QWG release (Michel)

gLite support

• CE tags publishing: fix for lcg-tags --sc
• CE configuration: allow different list of VOs on different CEs sharing the same gridmapdir

Monitoring

• Gather the information on existing Quattor-related probes at sites (Christos)
• Check problems in current monitoring templates for using them with icinga (UGant)
  • In the short term, ncm-icinga will be released and merged later

SCDB

• Use panc v9
• Prepare a SCDB release with new panc and new VOConfigTask

Aquilon

• Fix Kerberos issue in Aquilon appliance
  • 10/11: new ISO images uploaded + installation/walkthrough documentation added on the wiki.
• Demonstrate it can be used on various virtualization platforms (VirtualBox, StratusLab)

Web site

• Configure browsing of SF Git repositories on QWG Trac (Michel)

Miscellaneous

• Decide an action plan for implementing a more advanced change scheduling in Quattor: see discussion in Strasbourg and email discussion started by Gabor.
• Next workshop announcement
