Operations News

  • ORACLE succesfully upgraded to
  • CMS disk servers succesfully upgraded to SL5 64bit
  • Checksumming turned on for cmsWanIn on 2/2/11 and for everything else on 7/2/11
  • Fix for bad checksums (upgraded gridftp rpm) rolled out to lhcbMdst on 2/2/11 and for everything else (apart from Gen) on 7/2/11
  • New puppetmaster02 rolled out for all Quattorized disk servers on 3/2/11
  • Inactive job manager monitoring script rolled out to all primary job managers on 3/2/11
  • 2.1.9-10 installed on Preprod - testing can now start

Operations Issues

  • Lost tape CS7541. 78 files declared lost to LHCb. Remaining files were restaged as they were on disk.
  • Number of incompletely transferred LHCb files getting the wrong checksums increased until fix was rolled out, and checksums were corrected and the migration queue reduced.
  • A small number of files (<10) have been given wrong checksums, when they should contain '0000'. The same fix rolled out for LHCb helps with this bug as well.

Blocking Issues

  • Lack of production-class hardware running ORACLE 10g needs to be resolved prior to CASTOR for Facilities going into full production. Now being ordered.

Advanced Planning

  • Upgrade Gen disk servers to SL5 64bit and Quattorize the remaining non-Quattorized disk servers
  • CASTOR certification and upgrade to 2.1.10 and upgrade of SRM to 2.10 which incorporates:
    • fix for gridftp-internal to support multiple service classes, enabling checksums for Gen
    • fix to report files on draining disk servers accessed by FTS to be NEARLINE not UNAVAILABLE
  • Upgrade the NS to 2.1.10


  • Castor on Call person: Matthew
  • Staff absence/out of the office:
    • Chris (all week)
    • Richard (Mon,Tue,Thu)
