Site status

CSCS

Systems

• Phoenix working fine, good usage since last F2F
  • Some events:
    • cms06 issue (more storage details)
    • Swapping issue
• Main focus LHConCray knowledge transfer from Miguel

Storage

GPFS

• Last week inode incident
  • cms06 account reached ionodes quota
  • no impact on filesystem
  • some impact on cms jobs (related to the cms06 account)
    
    
• Stable operations, some peaks of load
  
  
• New servers arrived, will be installed, configured and integrated by the next week
  
  
• Will split GPFS in three clusters
  • Server-cluster
  • WN-cluster (remote)
  • LHConCRAY-cluster (remote)
    
    
• Will plan a maintenance to apply the new configuration in production

dCache

• New port parameters applied to all the pools (in the layout file); this will prevent any kind of port shortage/contention
• Had some problems with 2 CMS and 2 ATLAS pools that were unable to restart correctly.
• The twiki Phoenix Monitor Overview / Storage view has been updated. More updated plots from Grafana will follow
  
  
• New servers arrived
  • 1.5PB of new space will be to allocate
  • 1.1PB will be migrated and decommissioned
    
    
• dCache will be updated from v2.13.50 to v2.13.57 (xrootd and checksums improvements)

PSI

• Xxx
• Accounting numbers (from scheduler) from last month

UNIBE-LHEP

• ARC (5.2.1) instabilities (a-rex hangs, crashes, etc) ironed out by switching on the watchdog service, complemented by a rescue cron job running ever hour
• Occasionally must restart the services by hand (symptom: ARC CE network rates go to zero, but services seemingly up and running)
• Microboone resumed running on our resources, we are working on optimising the size of the glideins in order not to waste resources
• Microboone also now supported on the SE. Will keep a replica of the experiment raw data
• Ubelix CPU/WC efficiency largely recovered, will continue to watch it as at times it degrades sonsiderably
  
  
• HammerCloud status

• Accounting numbers (from scheduler) from MARCH 2017
  ATLAS: 942829 (was 792945 in Feb 2017); UBOONE: 16665 (was 6 in Feb 2017); UBOONE: 5083 (was 552 in Feb 2017); OPS:16
  
  
• Accounting numbers from ATLAS dashboard from last month (core-hours MARCH 2017) [1]
  CSCS / UNIBE: 60% / 40% (stable)
  
  
  • Efficiency WT ok/fail [2]
    CSCS 93% (was 93%) - UNIBE 81% (was 75%) (Ubelix getting better)
    
    
  • CPU/WT efficiency [3]
    CSCS 70% (was 90%) - UNIBE 81% (was 83%) (big dip for CSCS in the middle and end of the month: correlate to Reprocessing jobs [4] - Cmp. Bern [5] )
