Operations News

  • Upgraded grid-ftp RPM rolled out to CMS and LHCb
  • WAN tuning rolled out to all remaining service classes in CMS
  • Confirmation from CERN that we 'should' be able to upgrade NS to 2.1.10 with stagers on 2.1.9-6 - needs testing

Operations Issues

  • Callouts for low partition free space on SRM and NS, but neither had a production impact. Both being dealt with.

Blocking Issues

  • Lack of production-class hardware running ORACLE 10g needs to be resolved prior to CASTOR for Facilities going into full production. Been ordered. Servers arriving this week, RAID device mid-March.

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
