Issues & activities

  • Tier0 release 2.1.7 was not released due to the issues on monitoring. Andres decided that we should wait and fix the issues with Storage manager monitoring before changing headnode.
  • Andres replaced vocms001 certificates with the new ones located on /afs/cern.ch/user/c/cmscert/transfer, however they were unable to produce a proxy certificate on any machine, so Cristoph was asked to create new certificates. After he did it then the proxy certificates were generated on every machine.
  • German set up two replays and debugged some errors about it on vocms047. He ran a replay using 322963, one of the Heavy Ion run, with different configuration, as well as one with 327527, a run that is not on EOS to check the error messages produced by them. He set up FTS3 to transfer the files from CASTOR to EOS. Preparing to run 324841 (124TiB).
  • NodeSummary are showing error on the status but all components of that VM are working properly. A JIRA ticket was created on this issue JIRA . This is probably related to the openSSL version that does not have support .
  • DMWM jenkins is being tested on vocms047 now. Yunjae has been working on the reporting script to show more information on the JIRA tickets that we obtain from replays triggered by Jenkins. JIRA
