Operations Issues

  • Problem with CMS recalls - now fixed
  • c08 continuing being instable. Plan for removal from production
  • approx. 8 corrupt files discovered on gdss66 (cmsFarmRead) sent to CMS. None were critical.
  • entries on /etc/passwd disappeared on gdss67,110. Accedental redeployment?

Blocking issues

  • Lack of Quattor configuration files for SLC4.8 is stopping us evaluating Quattor alongside CASTOR 2.1.8. Preprod setup will initially proceed with a Kickstart-based deployment.

Planned, Scheduled and Cancelled Interventions

Entries in/planned to go to GOCDB

Description Start End Type Affected VO(s)
Upgrade of memory on database nodes (Ongoing) (Ongoing) At Risk All instances
Fix EMC multipath issues (Ongoing) (Ongoing) At Risk All instances

Advanced Planning
