General updates

Monday 25th June
Monday 11th June
- There is a pre-GDB Tuesday on benchmarking.
- There is a June GDB on Wednesday.
- HEPSYSMAN is next week 18th-19th June - so no ops meeting next Tuesday.
- Winnie – 8th June problem with argo-mon.egi.eu
- Progress towards running LSST DESC data challenge on GridPP. Lack of multicore option in DIRAC for per VO basis.
- DPM 1.10.2 update issue
- dCache and IPv6: GridFTP doors and pools require that if a client can connect to an IPv6 address on an interface, that interface should also have an IPv4 address to which that client can connect.
- Brian: requested input last week to Hardware for Grid SE page.
- Of note: VO vo.geoss.eu status from Pending to Production
- APEL: delay in processing VM accounting records and new cloud data appearing in the Portal during the week of the 11th to 15th June. This is so that the APEL Repository can be updated to correctly assign the usage VMs incur to individual months when they run over month boundaries (i.e. long running VMs). This requires reloading a large volume of existing cloud accounting data once the update has been applied.
- May A/R (waiting for replies to 6th June request):
- ALICE All OK
- Atlas RHUL 81% Lanc 86%
- LHCB RHUL 76% Bristol 74% (Availability only)
- CMS Bristol 77%
- WLCG weekly ops meeting minutes from Monday 11th.
- Today there are issues affecting the databases that GOCDB relies on, leading to very slow responses through the portal and API.
Monday 21st May
- CHEP 2018 registration is open until June 2nd.

Monday 25th June 2018, 15.00 BST
38 Open UK Tickets this week.
BRUNEL
133956 (9/3)
Any update for this CMS xroot ticket? The VO re-poked the ticket a few weeks ago and they were still seeing unwanted behaviour. In progress (15/6)
TIER 1
135455 (31/5)
CMS Checksums failing. After Chris cleared up some bad files it still looks like a few more persist at the last update. In progress (4/6)
135293 (23/5)
ROD ticket for Castor after the publisher was took offline. Daniela notes that the alarms have gone from the dashboard and asks if things are fixed - I believe that a new (if temporary) publisher was put in place? On hold (25/6)
SHEFFIELD
134947 (4/5)
Atlas file transfers. It looks like atlas are just reusing the old ticket for the latest batch of failures they are seeing. Reopened (11/6)
BRISTOL
134820 (29/4)
Can we please close this CMS ticket? The VO doesn't seem bothered with it. In progress (1/5)
RALPP
135552 (7/6)
CMS SAM test failures after a disk node hit some troubles. Taking a look at the test pages it's looking nice and green again so I suspect this ticket can be closed too.
ECDF
135404 (30/5)
Low availability ticket. Looking at the monitoring I see some more blue negative availability days in argo, so it looks like some weird stuff has been going on. It'll be a while before the alarm clears itself (especially as the weekend wasn't great), so this ticket could do with being put on hold. In progress (4/6)
