  • MCsimulation, Working Group Production tests and User jobs.
  • T0:
  • T1:
    • RAL : Jobs hitting CVMFS problems due to biomed jobs overloading some WNs (GGUS:105047). Thanks for quick action solving this issue.
    • GridKa : Some users not able to upload to GridKa-User SEs. Being investigated by LHCb GridKa contact - problem confirmmed by GridKa and will look at it on Monday.
    • GridKa : Problem accessing some files at GridKa (GGUS:105093)

28 April 2014 (Monday)

  • Incremental Stripping campaign finished - many thanks to all T1 sites !!!!
  • MCsimulation, Working Group Production and User jobs.
  • T0:
    • Migration of user data Castor -> EOS finished. Some minor problems in mapping users with production roles fixed by hand.
  • T1:
    • GridKa : Some users not able to upload to GridKa-User SEs. Being investigated by LHCb GridKa contact - will open GGUS ticket if needed.

24 April 2014 (Thursday)

  • Incremental Stripping campaign finished - many thanks to all T1 sites !!!!
  • MCsimulation, Working Group Production and User jobs.
  • T0:
    • Migration of user data Castor -> EOS started on Tuesday
  • T1:
    • GridKa : Some 102 input files for the stripping were not accessible to jobs, (GGUS:104852). Fixed Wed evening and jobs succeeded.

16 April 2014 (Thursday)

  • Stripping, MCsimulation, Working Group Production and User jobs.
  • T1:
    • IN2P3 : Last few files still staging for incremental re-stripping.
    • GridKa : Problem of uploading by jobs (GGUS:102920) possibly understood to be Alice bug overloading site SE/Network. Wait till next week to see if the problem is resolved.
  • Others : LFC very slow now. Lost x2 in speed since Oracle upgrade. Now response time ~400ms (was 100ms previously) (INC:0534625). Not clear from the ticket who is following this up.

14 April 2014 (Monday)

  • Stripping, MCsimulation, Working Group Production and User jobs.
  • T1:
    • IN2P3 : Downtime this morning for two CEs to upgrade openSSL. Not much effect on LHCb.
    • GridKa : Issue of aborted pilots (GGUS:103319) seems to have gone away. Problem of uploading by jobs (GGUS:102920) seems to continue.
  • Others : LFC very slow now. Lost x2 in speed since Oracle upgrade. Now response time ~400ms (was 100ms previously)

10 April 2014 (Thursday)

  • Stripping, MCsimulation and User jobs.
  • T0: 22nd april. migrations from CASTOR-USER to EOS-USER
  • T1:We still have no news about the delivery of the LHCb pledge at IN2P3 ???

7 April 2014 (Monday)

  • Stripping, MCsimulation and User jobs.
  • T0: Ticket re-opened with CERN to access CE.
  • T1: One user is not able to create directory on storage at PIC and Gridka. (will opene GGUS ticket)

3rd April 2014 (Thursday)

  • Stripping, MCsimulation and User jobs.
  • T0: one of our vobox had a kind of DoS from a Russian site yesterday . After we block th eIP range, the VOBOX was usuable.
  • T1: Pledge at GRIDKA will be provided soon, Thanks to PIC and RAL which provided new pledge.
