Tier-1 - Status Page
|
Tuesday 26th September
A reminder that there is a weekly Tier-1 experiment liaison meeting. Notes from the last meeting here
- There was a problem with the LFC service. A new node was added to the alias but it was not configured to support dteam VO. This was corrected in response to a GGUS ticket.
- A better understanding of CEPH problems with Echo has provided stability. However, careful management of the disks in servers recently added into Echo has been needed. This has slowed the rate at which the new hardware is being brought into full use.

Documentation - KeyDocs
|
Tuesday 19th Sept 2017
- Bug in Safari on macOS causes random Apple generated client cert to be presented to www.gridpp.ac.uk using a CA we don't know about. The connection is then rejected by Apache. Other browsers ok since we request but do not require that they supply a certificate. Workaround produced by (a) installing the Apple CA root and intermediary CA and (b) whitelisting UK e-Science DNs (+ CERN? Others?) in the HTTPS Wiki plugin. Tested but not yet in production.
Tuesday 5th Sept 2017

- This includes notifying of (inter)national services that will have an outage in the coming weeks or will be impacted by work elsewhere. (Cross-check the Tier-1 update).
Tuesday 4th July
- Pete C is preparing another networking forward look document. Note that figures presented in the Manchester workshop were for a Tier-2 (not always a single site).
Tuesday 6th June
- An update from the DIRAC workshop? GridPP is still the only true multi-VO instance, so we will continue to see issues with this. release quality of dirac has improved within the past year. gfal2/EL7 problems seem to be coming to an end after being cooped up with all authors for 3 days on end. The Imperial GridPP module now has integrated testing. It was also noted that every dirac instance has it's own special module to adapt to their community on top of main dira. We are trying to push as much of out special functionality back into the main dirac branch.
Tuesday 25th April
- perfSONAR version 4 was released on 17th April. Sites with auto-update on should have been automatically upgraded. Note perfSONAR 4.0 requires more CPU than previous versions as a result of some of the increased functionality. Full details here
- Duncan has recreated the UK perfSONAR mesh. Link here!

Tickets
|
Monday 25th September 2017, 15.00 BST
27 Open UK Tickets this week
TIER 1
128991 (16/6)
The Tier 1 chaps have finished enabling solidexperiment.org on the CASTOR tape system - although things aren't perfect with the argo tests (130537) there's an invitation to the VO to test the system. Waiting for reply (13/9)
IMPERIAL (rather, the DIRAC service)
130202 (24/8)
Dan from na62 is seeing their jobs spending too much time WAITING, particularly at the Tier 1. With some feedback from them it is thought that this could be due to fairshare - perhaps another case of expectation management is needed. John Kelly asks if there's still a problem. Assigned (should be something else) (25/9)
LIVERPOOL
130715 (24/9)
Liverpool have been having a bad time of it with their site firewall, and LHCB ticketed them about it. Steve has asked in the ticket the process that LHCB jobs connect back to their job hosts - information that would be good to record. In progress (25/9)
Also Liverpool have this OPS ticket you might have missed: 130698 (22/9)
BRISTOL
130646 (20/9)
On the subject of tickets that might have been missed, this CMS AAA ticket seems to have gone unnoticed at Bristol. Assigned (20/9)
