  1. FAX status report Ilija Vukotic Computation and Enrico Fermi Institutes University of Chicago ADC Development Meeting April 28, 2014

  2. Content • Meetings • We need to get back into “right” week. Again next week? • Pre-GDB contribution? • CERN week 2-6 June • Tutorial – 23 -27 June – dedicated to instructing on xAOD and the new analysis model • ROOTIO – 25-27 June • Status • Traffic • Failover • Change in federating direct dCache • Overflow status

  3. Status • Most sites running stably • Glitches happen but are fixed usually in less than a day • All monitoring tools running stably. • RALPP – disabled due to lack of support • RHUL – will disable if not back to green during next week

  4. Failover • Running stably • A lot of churn on the failover top list • Still to discuss how to inform sites on too frequent failovers

  5. Change in federating direct dCache • Up to now directly federating dCache xrootd doors required a “helper” with two pairs of xrootd/cmsd services • A redirector plugin developed • Enables native dCache upstream redirection • Delivered with dCache N2N plugin (same rpm) • Simplifies configuration, improves redundancy • Documented in TWiki • A very nice document, detailing dCache in federation written by Andy • http://www.slac.stanford.edu/~abh/Fed-dCache/fed_dCache.pdf • MWT2, AGLT2, SFU already using the new method

  6. Overflow status • All the chain untill pilot tested • HC test with transfertype=fax are now running as expected • FT FAX direct rc_test : Simple histogram making 17.5.0, Local DS,transfertype=fax • Waiting for a production pilot to re-start scheduling jobs to overflow (Tuesday) • After running it for a week we will test how well limiting bandwidth works (wanlimitsource, wanlimitsink).
