Next scheduled release is February's UMD 4.10.0: https://wiki.egi.eu/wiki/UMD_Release_Schedule

• integration of HTCondor-CE still in progress
• HTCondor-CE released in UMD 4.9.1 http://repository.egi.eu/2019/12/04/release-umd-4-9-1/ pointing to the original documentation (the documentation is OK)
• still needed to contributed to the WN package
• there is no particular automatic way provided to EGI sites to configure HTCondor-CE
• UMD team offers automatic deployments for several well-known products and is willing to provide such kind of recipes; usually these recipes are a result of a * joint effort of the provider together with the UMD team
• Are NGIs willing to investigate among their site admins about condor/HTCondor-CE skills and contribute with available recipes or help?

CMD

Still needs to be restarted

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"
