Liasing with WLCG to follow-up the upgrade. Opened GGUS tickets asking the following:

• all the sites with older DPM versions than 1.12 are suggested to upgrade to the latest DPM version , following the guide DPM upgrade (chapter 1 Upgrade to DPM 1.10.0 "Legacy Flavour" and chapter 2 Upgrade to DPM 1.10.0 "Dome Flavour")
  • DOME and the old LCGDM (srm protocol) will coexist
• Monitoring: sites should enable the monitoring of the HTTP/WebDav and/or GridFTP endpoints
  • register the storage service endpoint as webdav and/or globus-GRIDFTP service type, with production flag disabled, providing respectively the URL field and the Extension Properties information as explained in the HOWTO21
  • check if the tests are ok
  • switch the production flag to "yes"

List of tickets:

• DPM upgrade, DOME enabling, and monitoring (33)
• enabling DOME and proper monitoring (6)

    • HTCondor-CE is released with HTCondor in a version without the dependencies on other OSG software. Moreover, HTCondor-CE depends on HTCondor (though not for use as a batch scheduler), so both packages will need to be distributed.
  • Asked for any automated deployment (ansible, puppets or other) configuration files supported by HTcondor team
    • It is available a copy of the ansible files that OSG uses to configure HTCondor-CE on their internal testbed machines. They can provide help for a non-OSG version of the files
  • Provided information for the UMD card: https://wiki.egi.eu/wiki/UMD_products_ID_cards
