LCGDM end of support and migration to / enabling of DOME (TO UPDATE)
- The DPM team has agreed to extend support for security updates for the DPM legacy functionality until 30 September 2019. However, affected service providers should still plan to disable legacy mode well before this date.
- more details: https://wiki.egi.eu/wiki/DPM_End_of_legacy-mode_support
- since DPM 1.10.3 release, it is possible enabling the non-legacy mode DOME (Disk operations Management Engine, see documentation)
- latest DPM release 1.13.1 has been also released in UMD 4.8.5
- EGI Operations sent a broadcast to site-admins(first bunch and second bunch) and VO managers with a survey to fill in:
- site-admins: to know the upgrade plans: https://www.surveymonkey.com/r/2PBZSNB
- VO Managers: to know any barriers in moving away from using SRM protocol https://www.surveymonkey.com/r/2ZMZJVG
- Deployment statistics (Oct 10th):

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)
- tickets opened by WLCG: 13 and 7

- (in progress) Information System: the info-provider is already available: https://github.com/opensciencegrid/htcondor-ce/tree/master/contrib/bdii
- to test during the staged rollout
- (in progress) Monitoring: some probes are already available that submit jobs to CondorCe, CREAM and ARC-CE:
- https://gitlab.cern.ch/etf/jess

- Condor team filled in the questionnaire and sent it to Linda
- (in progress) UMD
- suggested to act in advance because the functional tests could take a lot of time
- Ticket for the inclusion: https://ggus.eu/index.php?mode=ticket_info&ticket_id=139764
- 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
- plan to release by the end of the month
