WLCG-OSG-EGEE Ops' Minutes Wed 16 Sep 2009

Summary

Call to encourage sites to move to the most recent version of WMS available in gLite 3.1, which corresponds to glite-WMS 3.1.21-0 in the gLite repository (known with the nick name of WMS 3.2)
Last month several alerts were sent to all sites about critical security vulnerabilities in the Linux kernel (CVE-2009-2692 and CVE-2009-2698). A number of sites in the academic community have subsequently reported root compromised hosts via these vulnerabilities. Yet, it appears a significant number of EGEE sites have still not applied the security patches - it is essential to actively and urgently ensure all the sites in your region have applied these security patches.

Attendance

No record of attendance because most of the attendees were phone numbers, difficult to match with names/ROCs/sites.

We'll try to find a solution to this for next meeting.

Feedback on Last Week's Minutes

None was given.

REMINDER: Security vulnerabilities

Last month several alerts were sent to all sites about critical security vulnerabilities in the Linux kernel (CVE-2009-2692 and CVE-2009-2698). A number of sites in the academic community have subsequently reported root compromised hosts via these vulnerabilities. Yet, it appears a significant number of EGEE sites have still not applied the security patches - it is essential to actively and urgently ensure all the sites in your region have applied these security patches.

IMPORTANT: call to upgrade WMSs to version 3.1.21-0 in the gLite repository

Call to encourage sites to move to the most recent version of WMS available in gLite 3.1, which corresponds to glite-WMS 3.1.21-0 in the gLite repository (known with the nick name of WMS 3.2) This update contains a new release of the WMS which is a complete redesign of the service. For a summary of the changes introduced in this version, please check these web pages: https://twiki.cnaf.infn.it/cgi-bin/twiki/view/EgeeJra1It/ReleaseNotes2597
http://web.infn.it/gLiteWMS/index.php/information/38-software/59-320relnotes
NOTE that at last week's GDB, WLCG asked sites to move to this version of WMS by the end of October. This would be a request to EGEE as well as a change to the WLCG Base Level Version. At that time all CREAM CEs would be flagged as production in the BDII. When this happens, anyone using a previous version of WMS risks their jobs matching with a CREAM CE and thus failing. Before then people need to direct work at CREAM CEs explicitly (even through WMS).

problems with APEL accounting when deploying a cream ce

Question from Pierre Girard, IN2P3 (France) about problems with APEL accounting when deploying a cream ce in production. There is a known problem for which the produced accounting logs (used by APEL and DGAS) was not properly filled if the CREAM CE is not the Torque server. A patch solving this is in the release chain (CREAM CE 1.5. PATCH:2666)
