Operations News

  • Now increased the threads on ATLAS Stager and Transfermanager (in addition to the NS) in an attempt to reduce occurrences of "threads busy with CASTOR" errors we see on the SRMs. The number has gone down, but it is unclear whether this is due to lighter load.
  • T2K's tape recall problems have been fixed by some adjustments to CASTOR settings and an increased timeout on the transfers.
  • The new disk server generation will be deployed into preprod for CASTOR testing in the next week.

Operations Problems

  • We had some CMS SUM test failures between Tuesday and Thursday which were believed to be due to load on the disk servers.

Blocking Issues
