Week of 140203

WLCG Operations Call details

• At CERN the meeting room is 513 R-068.

• For remote participation we use the Alcatel system. At 15.00 CE(S)T on Monday and Thursday (by default) do one of the following:
  1. Dial +41227676000 (just 76000 from a CERN office) and enter access code 0119168, or
  2. To have the system call you, click here

• In case of problems with Alcatel, we will use Vidyo as backup. Instructions can be found here. The SCOD will email the WLCG operations list in case the Vidyo backup should be used.

General Information

• The SCOD rota for the next few weeks is at ScodRota
• General information about the WLCG Service can be accessed from the Operations Web

Experiments round table:

• ATLAS reports (raw view) -
  • Central services/T0
    • CERN_PROD: Transfers were failing with permission denied errors on Monday morning. Noticed and fixed by CERN team. Thanks.
  • T1
    • TAIWAN: heavy SRM load caused transfer failures on Sunday (GGUS:100904).Fixed.
    • FZK: staging errors for DATATAPE on Friday (GGUS:100885). Fixed by issuing a retry for all outstanding stage requests for ATLAS and restarting tape storage software.
    • pic: problem with one disk pool, which caused transfers to failed on Friday (GGUS:100874), dCache pool restarted.

• CMS reports (raw view) -
  • T1/T2/Others: Bussiness as usual. Smooth running.
  • Preparing for DBS (data catalog) upgrade on Feb 10. That week will see little to no central processing
  • One problem: ARGUS cluster issue(s) (DNS? and then a new, uninitialized node in the cluster) caused problems with analysis jobs running.
    • Debugged by CMS analysis operations. Better would be to have SLS monitoring of the ARGUS cluster.

• ALICE -
  • sites please take note of the necessary WLCG VOBOX update announced last Fri
    • see details below
  • KIT
    • the number of corrupted files has shrunk by 45% to 26126
    • 21k files have been salvaged after all, thanks very much!

• LHCb reports (raw view) -

• WLCG VOBOX
  • as announced on the wlcg-operations list last Fri, please ensure your WLCG VOBOX instances generate host proxies with 1024-bit keys!
  • preferably update Globus; correct minimal versions of the affected rpm:
    • globus-proxy-utils-5.0-6 (Globus 5.0)
      • UMD-3 SL6 rpm (can be installed manually also on UMD-2 machines)
      • UMD-3 SL5 rpm (ditto)
    • globus-proxy-utils-5.2-1 (Globus 5.2)
      • from EPEL for EMI-3 and EMI-2
  • otherwise one can apply this quick hack:

            perl -pi.bak -e 's/ -q / -bits 1024 $&/' \
                /etc/vobox/templates/voname-box-proxyrenewal \
                /etc/init.d/*-box-proxyrenewal
