2. ACTIVITY REPORT

2.1. Progress Summary

Regular maintenance of national SAM/Nagios, Top BDII, national operations portal. There were no problems with new top-level BDII round robin setup.

2.2. Main Achievements

New disk array (66TB) at prague_cesnet_lcg2 put in production.

New WMS/LB service installed solely for monitoring purposes. New LB machine lb1.grid.cesnet.cz installed with EMI middleware, it will phase out the glite LB at lb2.egee.cesnet.cz. All lcg-CE nodes phased out and switched off on praguelcg2 and prague_cesnet_lcg2. The lcg-CE service has been completely replaced with creamCE from EMI mw.

prague_cesnet_lcg2 has updated worker nodes to EMI mw and since that we have been using torque developed at Metacentrum with several interesting features (monitoring slots for OPS jobs, scalability).

praguelcg2 has updated worker nodes to EMI mw as well. The upgrade was accompanied with installation and configuration of CVMFS - special filesystem for Atlas software distrubuition.

Many production services have been upgraded to EMI middleware, but there are still some to be finished.

Performed regular activities of EGI CSIRT, including duty shifts and attendance to regular meetings. Coordination of security monitoring activies, mainly focused on utilization of the security dashboard, which was put into pilot utilization.

Adaptations of the Pakiti monitoring have been applied (better integration with the security dashboard, providing customized Pakiti probes for sites, etc.)

2.3. Issues and mitigation

Issue Description Mitigation Description
In November our availability numbers were affected by problems on WMS. The monitoring jobscould not reach CEs and so the status of CEs was "unknown". We have taken two steps to solve this:
  • new WMS/LB node wms3.grid.cesnet.cz has been installed so the problems of CEs are not masked/falsely raised

by production WMS problems.

  • production WMS nodes have been updated to EMI mw version
