| General updates
|
Tuesday 3rd March
- There was an EGI OMB last Thursday. Highlights for awareness:
- EGI core activities to be reviewed for next phase.
- EGI provides a catch-all CA; Request to register iRODS endpoints in GOCDB; EU Brazil Cloud Connect mentioned; May conference registrationopen. Next OMB 26th March.
- Check the status of multi-core publishing.
- New release of ops portal coming 16th March. See Schedule and version 3.1.2 changes.
- New performance documents. QoS; ROD; Availability/Reliability.
- Security: FedCloud survey done. EGI-CSIRT collaboarating with FedCloud. Security challenges coming - communications one done; next pull in payload and assess capabilities. Also looking at VM incident handling.
- ARGO monitoring: Modular architecture. Example deployment models given for EGI/VO/NGI. Uses message brokering - between collectors and review engine. Listed advantages over ACE. Problems with SAM Nagios given (e.g. effort to upgrade, support). ARGO is SAM refactored (no heavy DB). -> Need a UK view on this as being pushed for EGI-Engage.
- VO SLAs: to clarify expectations. Some updates including FedCloud inclusion.
- EGI Engagement (strategy): Call for unfunded partners to join core competency centres: BBMRI, DARIAH, EISCAT_3D, ELIXIR, EPOS, INSTRUCT, LifeWatch & Disaster mitigation.
- New infrastructures in preparatory project phase: MIRRI – microbal resources; EuroDISH – food, nutrition, diseases; ISBE – systems biology. Opportunities for national engagement: EMBRC: Marine biological resource centre (... + UK); ERINHA: Highly Pathogenic Agents (...+ UK); Euro-BioImaging (...+ UK & EMBL).INSTRUCT: Structural biology (many countries). CLARIN (call out).
- Genome analysis & protein folding pilot ongoing: Chipster, RSAT, READemption.
- Ongoing integration of ELIXIR reference datasets into EGI. Several use-cases for FedCloud mentioned (any more sites want to join?)
- Preliminary agendas are available for the pre-GDB and GDB.
- The deadline for CHEP registrations is 15th March. (Bulletins)

Tuesday 3rd March
- The problems with our primary network router are still being followed up. We have a spare switch and plan to try this out early on Thursday morning (5th March). An 'At Risk' has been declared in the GOC DB.
- Also on Thursday morning there will be an upgrade of the FTS3 service (to version v3.2.32).
- Last Tuesday we moved a number of Castor disk servers physically within the machine room. This was required to make space for part of the new deliveries.
- On Wednesday next week (11th March) we plan to update the firmware in our network switches to fix a problem of periodic reboots.

| Storage & Data Management - Agendas/Minutes
|
Tuesday 3rd March
- DiRAC FS backup to RAL (and UCL) very likely to go ahead. GridPP encourages support from co-located sysadmins to help setup transfers... but first there needs to be a discussion of how the data will be handled. More soon.
Monday 23rd February
- From February 17th expect xrootd version 4 will be added to the EPEL repository. Update not transparent if xrootd supported.
Tuesday 17th February
- Chris suggests linking the WebDav page from the storage wiki.
|
| Documentation - KeyDocs
|
See the worst KeyDocs list for documents needing review now and the names of the responsible people.
Tuesday 3rd March
- Proposals for about 4 keydocs to be removed/downgraded. For discussion at next core-ops or focus meeting.
Tuesday 24th February
Tuesday 17th February
- KeyDocs review continues. Deadline for removals requests 25th February.
Tuesday 10th February
- Survey of KeyDocs has started. If you own a document please take note. Documents remaining after this exercise will need to be brought fully up-to-date.
- A reminder that Steve created this Current Activities capture page. Only ARGUS at the moment!?
- See also the documents from Tom linked in the 'Other VOs' section.
Tuesday 3 Feb
- New section in Wiki called "Project Management Pages".
The idea is to cluster all Self-Edited Site Tracking Tables
in here. Sites should keep entries in Current Activities
up to date. Once a Self-Edited Site Tracking Tables has
served its purpose, PM to move it to Historical Archive
or otherwise dispose of the table.

| Interoperation - EGI ops agendas
|
Monday 9th February
- The agenda for February's EGI ops meeting is here.
- Argus PAP update (1.6.2) out imminently. This should fix the SSL problems for sites affected after a java update. Hopefully this will solve Raul's problems in his ticket 111505.
- Other update notifications include APEL 1.4.0 (with a bunch of new features), Storm 1.11.6, UNICORE v7.2.0 and a new version of Globus in EPEL testing. UMD release 3.11.0 being prepared.
- Multicore republishing was discussed - if sites need to republish multicore data previously parsed as single core then they need to reparse the logs. Any site wanting to republish is asked to submit a ticket to apel support first.
- Operational issues were discussed whereby sites saw problems running ARGUS and CREAM on the same node, special care is taken if you want to take this mad path. See tickets 111464 and 111373.
- The decommissioning of the EMI2 APEL service and the UMD repositories was mentioned.
- Sites are advised to avoid using MySQL v.5.0 where possible.
- A comment was passed that the EPEL5 repository was becoming harder to keep up to date, bringing the effective EOL of SL5 closer for the community
- SL7 is a topic that still needs to be discussed in earnest in this forum.
- Next meeting is March 9th - effort to keep the number of meetings down.

Tuesday 17th February
- A message from Maria Dimou: A request to you and the sites you collaborate with, to please install the MW Package Reporter.
The current version, documented in the wiki , it
is very easy to install and addresses all site and security requirements.
- Quick check on: 1. ARC CE readiness testing. 2. Machine job features testing.
Tuesday 20th January
- From Cristina's GDB talk last week note that EMI repositories will be frozen and the product team releases will become UMD-preview (repository content and webpages similar but now managed).

| Tools - MyEGI Nagios
|
Tuesday 17th February
- Another period where message brokers were temporarily unavailable seen yesterday. Any news on the last follow-up?
Tuesday 27th January
- Unscheduled outage of the EGI message broker (GRNET) caused a short-lived disruption to GridPP site monitoring (jobs failed) last Thursday 22nd January. Suspect BDII caching meant no immediate failover to stomp://mq.cro-ngi.hr:6163/ from stomp://mq.afroditi.hellasgrid.gr:6163/

| VOs - GridPP VOMS VO IDs Approved VO table
|
Tuesday 17th February
Two changes to approved VOs (https://www.gridpp.ac.uk/wiki/GridPP_approved_VOs)
- LSST uses port 15003 (had been 15002, clashing with dzero)
- t2k has included a note that it';s software is now distrinuted via CVMFS.
Tuesday 17th February
- Some interest from UK LIGO users. Catalin setting up CVMFS. Issue with VOMS. "Our users have access to CILogon basic CA certificates, which I understand can in principal be entered into VOMS to provide a VO identity."
Tuesday 10th February
- There is now a Quick Guide to CVMFS.
- Part of Tom's quick guide series! There is also a Quick Guide to DIRAC.
- Feedback on both welcome... on the CVMFS front some mapping issues for regional VOs are being examined.
- GalDyn (UCLan galaxy simulations): test jobs have been submitted via DIRAC; now moving onto data storage testing via the official DIRAC tutorials.
- CERN@school has its first student on the grid with a grid certificate! LUCID data arriving.
- The CERN VM mechanism looks like it could provide an interesting way for new users to get a grid-ready UI by installing VirtualBox (or similar), downloading the CERN VM image, and applying a GridPP-specific context.
