Topics for this week

  • Storage Status -
    • Overall space availability looks OK
    • Storage reporting looks OK, except some irregularities at SLAC space tokens, but looks like that is recovering.
    • Deletions look OK. Proddisk cleaning at US sites is temporarily disabled (related to BNL data recovery effort).
    • SSB notification issue followed at: https://savannah.cern.ch/support/?136561
    • SAAB blacklisting email to be sent to atlas-support-cloud-us for all major US sites. Looks like that was the agreement. Was that already put in AGIS. Check with Rob.
  • Dark data -
    • Long discussion on various options to cleanup userdisk dark data. Do full consistency check or just go simple way and use info from storage dump.
    • Last version of the ccc script. Check what are site using.
    • Space consumption per user for MWT2_UC_LOCALGROUPDISK and SLACXRD_LOCALGROUPDISK, tables attached
    • Generally more than 70% of the datasets in those space tokens have not been used at least a year.
  • USERDISK cleanup -
    • Notifications for the next userdisk cleanup were out on June 30. Cleanup will run end of this week.
  • Hot issues
  • AOB
