Example alt text
Merry Xmas!
  • RAL is closed after Friday afternoon 22nd December and will re-open on Tuesday morning 2nd January. Plans for the holiday period follow the pattern established over recent years and we will try and respond to urgent service-affecting events. The Tier1 on-call team will be in place throughout the holiday and will respond to alerts as usual. They will also carry out some additional checks throughout this period. The Machine Room and network operations teams will also be providing on-call cover during the holiday. However, please note that support will be limited on Christmas Day, Boxing Day and New Year’s Day.
Review of Issues during the week 13th to 20th December 2017.

Echo: • Background scrubbing has been going on. This has flushed out more bad disks – causing some callouts through the week.

Network: • Emergency card replacement at Harwell PoP on Thursday morning. This was announced to us and caused a short break in two out of the three OPN links (as expected)


Current operational status and issues
  • None
Resolved Castor Disk Server Issues
  • GDSS743 (AtlasDataDisk - D1T0) is back in production.
  • GDSS705 (AtlasTape - D0T1) is back in production.


Ongoing Castor Disk Server Issues
  • None
Limits on concurrent batch system jobs.
  • CMS Multicore 550
Notable Changes made since the last meeting.

Infrastructure: • There was a successful generator load test last Wednesday (13th Dec).

Certificates: • The re-updating to pick up the updated UK CA certificate in the IGTF 1.88 rollout took place successfully last Tuesday (12th) as planned.

Castor: • Three Castor disk servers were moved from LHCb tape buffer to their disk-only (D1T0) storage.

Entries in GOC DB starting since the last report.

No downtime scheduled in the GOCDB between 2017-12-12 and 2017-12-20

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.

Ongoing or Pending - but not yet formally announced:

Listing by category:

  • Castor:
    • Update systems (initially tape servers) to use SL7 and configured by Quattor/Aquilon.
    • Move to generic Castor headnodes.
  • Echo:
    • Update to next CEPH version ("Luminous").
  • 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).
