      Data Management
      Speaker: Armen Vartapetian (University of Texas at Arlington (US))

      Issue with SWT2_CPB reporting for DATADISK and SCRATCHDISK. Need a fix as deletions are working hard to compensate for that missing space.

      The missing data in DDM accounting dashboard for the last 3 months finally repopulated (SNOW ticket INC1705039), as it became urgent to be able to produce plots (S&C week). Next week we’ll have a dedicated meeting for the new monitoring page replacing the current one.
