Meetings & updates - ROD team update - EGI operations update (thanks to Stuart P) "EMI-1 software release: WMS: On the 17th there was an emergency release of WMS 3.3.1 - addresses a vulnerability CREAM: Release expected on 23rd to fix infinite loop with argus integration. Storm: Not now expected to be released for the 23rd June; delayed. (Might make next update release on 7th July ?) Next major update is expected on the 7th July, for components that get released to certification before 27th June. If they don't make it then it will be 2 weeks later. Detailed list of planned release in: https://www.egi.eu/indico/getFile.py/access?contribId=0&resId=0&materialId=slides&confId=495. Includes L&B, WMS and Argus updates. Some discussion on tickets, and tracking of these - in particular who is responsible for making sure that tickets are also cc'd to the Release managers. Mario will be updating procedures to make this clear (it's the staged rollout managers). UMD/Staged rollout: Useful table at https://wiki.egi.eu/wiki/Agenda-20-06-2011. Moving UMD release announcement from 4th to 11th July Operational Documentation: On how to migrate a service preserving it's state. A survey was done of what is present, and what more is needed; work is underway. Consideration of this issue for ARC and Unicore. This will be added as a requirement for EMI." - Nagios status Tier1 comments from this last week. ============================ Some problems with the CMS Castor instance last week (Wednesday). Load issues in the LSF scheduler that is used internally within Castor. 90minutes unscheduled downtime declared. Thursday: The DB team reported that intervention to update an Oracle and a system parameter on remaining Castor database nodes went OK. Although too early for confirmation this should fix a problem to do with gathering the database statistics. Over the weekend we had a problem with LHCb SRMs. We also had a problem with CERN information missing from our top BDIIs. There have been a couple of disk server problems in the last week. (One for Alice, one for LHCb). No data loss We are looking to apply a partial update to Castor in order to prepare for the higher capacity "T10KC" tapes. This is likely to take place on Tuesday 5th July during the LHC technical stop. We are also rolling out a newer version of the Castor clients across the worker nodes as soon as practical. At LHCb's request we have increased the maximum wall clock limit on our 6GB queue by 20% (to 120 hours). - Security update Torque vulnerability follow-up -- T2 issues --- Accounting (http://www3.egee.cesga.es/gridsite/accounting/CESGA/egee_view.php).

Site roundtable (glexec focus) - Note the the gLExec deployment page has been updated: https://twiki.cern.ch/twiki/bin/view/LCG/GlexecDeployment. (Glasgow's SCAS/glexec wiki entry http://www.scotgrid.ac.uk/wiki/index.php/Glasgow_GLite_gLExec_installation_and_configuration).

Core ops team task areas - Ahead of the team discussion of the task areas it would be useful to work with individuals in the core team to gather additional ideas and to develop the descriptions in the wiki. Areas (http://www.gridpp.ac.uk/wiki/Category:GridPP_Operations) are: - Staged rollout - On-duty coordination - Ticket follow-up - Regional tools (Kashif+?) - Documentation - Security (Alessandra/Jeremy) - Monitoring - Accounting - Core grid-services - Wider VO-services There will be other areas like incident follow-up, coordination with other grids (Stuart?) that may appear explicitly.
