Monday 17th September

• There was a WLCG ops coordination meeting last Thursday. The minutes are now available and the presentations uploaded to this agenda page.
• Highlights:
  • A report on EOS incidents, improvements and plans
  • DPM Storage Resource Reporting deployment TF introduction
  • CMS CRIC is deployed in production
  • Sites should upgrade perfSONAR to v4.1 on CentOS 7
  • The next meeting is planned for 11th October.

Tue 13th November Report for the Experiments Liaison Report (13/11/2018) is here.

• We have noticed that our CV17 storage nodes have been randomly rebooting. These nodes are not fully weighted up in Echo and further increases have been stopped while the problem is sorted out. A firmware update is being pushed out. Machines that have the new firmware appear to be fixed, but we are still gathering statistics. It should be noted that there has been no observed impact from the user perspective.
• On 7th November, the first LHCb space token was migrated from Castor to Echo. This is the FAILOVER space token which is used by jobs from other sites if their storage is down.
• NA62 were successfully migrated to the new consolidated Castor tape instance.
• ATLAS are unable to get their jobs via singularity to work. We believe this is because they require privileged containers and we are currently only offering unprivileged ones. We would hope that ATLAS could improve their code.
• CMS AAA issue remains ongoing, but we believe the situation is improving. We updated the XRootD version to fix a known bug on Friday and the amount of red in the SAM tests dropped over the weekend.

Wed 14 Nov

• Interesting operational issue switching ATLAS from SRM to xroot
• Do we have a "data management solution" and if so, what does it look like?

Tuesday 22rd October

• VacMon monitoring pages running again, on CentOS7/ES5. Still slower than previous SL6/ES5 machine so may try again in a larger memory VM.

Tuesday 16th October

• Vacmon was working for a while but is now timing out. AM looking at ways of downgrading back to the previous version for now.
