RAL Tier1 Operations Report for 4th June 2018

Review of Issues during the week 28th May to the 4th June 2018.
  • No incidents(major or minor), have been flagged during this reporting period.
Current operational status and issues
  • For the avoidance of doubt regards confusion over the status of both the BDii and Castor services. Tier-1 have NOT stopped or decommissioned these services. What has changed is that the Castor information stopped getting published in the BDii. This was due to a failure of the machine running the Castor Information Provide (CIP). The CIP was a legacy part of Castor (It didn't support GLUE2 schema), and was due to be decommissioned, the hardware failure expedited this issue. Although we admit this is not ideal, we decided against bringing back a service simply to then inform people we would shortly remove it.
Resolved Castor Disk Server Issues
  • gdss801 - cmsDisk - d1t0. Currently back in production RO.
  • gdss817 - LHCb - d1t0 - Currently back in production RO.
  • gdss733 - LHCb - d1t0 - Currently back in production RO.
Ongoing Castor Disk Server Issues
  • None.
Limits on concurrent batch system jobs.
  • CMS Multicore 550
Notable Changes made since the last meeting.
  • None.
Entries in GOC DB starting since the last report.
  • None
Declared in the GOC DB
  • None
Advanced warning for other interventions
The following items are being discussed and are still to be formally scheduled and announced.

Listing by category:

  • Castor:
    • Update systems to use SL7 and configured by Quattor/Aquilon. (Tape servers done)
    • Move to generic Castor headnodes.
  • Networking
    • Extend the number of services on the production network with IPv6 dual stack. (Done for Perfsonar, FTS3, all squids and the CVMFS Stratum-1 servers).
  • Internal
    • DNS servers will be rolled out within the Tier1 network.
  • Infrastructure
    • Testing of power distribution boards in the R89 machine room is being scheduled for some time late July / Early August. The effect of this on our services is being discussed.
