Review of Issues during the week 7th December to 13th December 2017.

Castor: • On Wednesday (6th Dec) all the SRMs systems (except LHCb – which had already been done) were successfully upgraded to the latest version (2.1.16-18) • Three disk servers (old ones from 2012) have been added to the LHCb Disk-only space in Castor to alleviate problems of this area being too full.

Echo: • The maximum number of gridftp connections to each Echo gateways has been increased to 200 (from 100). • Echo is running normally. Background scrubbing is going on. This is flushing out bad disks – and the rate at which it finds these is expected to drop over the next week or two. The plan is to run like this through the holiday period.

Services: • EGI will withdraw support for the WMS from the start of 2018. Our WMS service will be stopped on this timescale.

Network: • There was a problem of high packet loss for traffic to/from the Tier that passed through the RAL core network (and firewall) on Monday (4th). The problem started at midnight and was fixed around 15:30.

Infrastructure: • Following the failure of the generator to start during the power outage of a couple of weeks ago a faulty emergency power-off switch was found and has been replaced. Planes are being made for a generator load test – hopefully on Wednesday (13th Dec).

Certificates: • Following problems with the updated UK CA certificate in the IGTF 1.88 rollout we had updated and then rolled back. This had left is with some issues in our configuration/deployment system (Quattor/Aquilon) – but those were resolved quickly. We made a plan to roll forward again tomorrow (12th Dec) – and that is still the plan.

Christmas Plans: • We will follow the same pattern as in previous years. The on-call team will be in place as usual. Some additional checks will be made by those on-call. RaL is closed after Friday afternoon 22nd December and will re-open on Tuesday 2nd January.
