Monday 16th January
- Rota to be updated this week. Gordon is on shift this week.
Monday 9th January
- Daniela posted on 25th Dec to say: "there's quite a lot of tickets - I tried to extend them all into January.
Otherwise apparently the grid is still standing."
Monday 5th December
- Another fairly quiet week. There were a few new tickets, which are mostly now resolved. There was an intermittent SRM alarm at RALPP which sporadically appeared then disappeared; it finally hung around long enough today to raise a ticket.

Monday 13th February 2017, 16.00 GMT
25 Open UK Tickets this Week
ATLAS want your INPUT
126184 (26/1)
Atlas request for input on sites monitoring. In last week's cloud meeting Alastair asked if anyone had any input for this. If you do feel free to add to the google doc linked in the ticket or email your points to the cloud support mailing lists. In progress (7/2)
TOKEN AFFECTION
126554 (10/2)
Sno+ jobs failed at Liverpool, and once again John B had to educate a user group that space tokens are a thing (thanks John!). Would everyone who supports Sno+ be willing to roll out a space token for them? We don't know at this stage how much space would be needed, at this point it mainly seems for job stage back. In progress (13/2)
UNRELIABLE AVAILABILITY
126349 - ECDF
125743- RALPP
Both of these availability tickets are confusing the sites and myself (although the latter is still quite easy to do). ECDF are getting negative results again (and a lot of unknowns) and RALPP seem to be not updating results very often at all, suffering a several day lag by the looks of it.

| Site Updates
|
Tuesday 23rd February
ALICE:
All okay.
RHUL 89%:89%
Lancaster 0%:0%
RALPP: 80%::80%
RALPP: 77%:77%
- RHUL: The largest problem was related to the SRM. The DPM version was upgraded and it took several weeks to get it working again (13 Jan onwards). Several short-lived occurrences of running out of space on the SRM for non-ATLAS VOs. For around 3 days (15-17 Jan) the site suffered from a DNS configuration error by their site network manager which removed their SRM from the DNS, causing external connections such as tests and transfers to fail. For one day (25 Jan) the site network was down for upgrade to the 10Gb link to JANET. Some unexpected problems occurred extending the interruption from an hour to a day. The link has been successfully commissioned.
- Lancaster: The ASAP metric for Lancaster for January is 97.5 %. There is a particular problem with ATLAS SAM tests which doesn’t affect the site activity in production and analysis and this relates to the path name being too long. A re-calculation has been performed.
- RALPP: Both CMS and LHCb low figures are due to specific CMS jobs overloading the site SRM head node. The jobs should have stopped now.
