Operations News

  • ATLAS upgraded to 2.1.11-8
  • Puppet upgraded to 2.7.11-1
  • 'go-faster stripes' enabled on all 'B' and 'C' tape drives
  • preprod now configured with lcgc*03 headnodes (destined for Gen) + preprod NS for Alice xrootd testing
  • preprod SRMs now configured with updated RPMs and ready for testing. It is hoped that this will help improve the periodic crashing.

Operations Problems

  • ATLAS SRM periodic crashing continuing. Restarter didn't kick in on Thursday, leading to a short time being blacklisted.
  • cleanLostFiles running against 5 disk servers caused stager slowdown on Thursday evening. From now on we will run no more than 3 cleanLostFiles threads and none out of hours.

Blocking Issues

  • none
