Alexandre gave a talk about this project at the DIRAC-Rucio workshop: https://indico.cern.ch/event/1252369/contributions/5515420/attachments/2735… If you have any input to this from a *user* (as opposed to an admin) perspective could you please consider submitting it here: https://github.com/DIRACGrid/diracx-web/discussions Depending on your fondness for modern development tools, you can submit a "User personas and Stories" which should (hopefully) capture all the background information needed by the developers for your request. (The form is a lot more straightforward than the title suggests !) If that all seems too much, you could just drop Alexandre (in the cc) an email, and he'll make a story for you. Thanks, Daniela -- ----------------------------------------------------------- daniela.bauer(a)imperial.ac.uk HEP Group/Physics Dep Imperial College London, SW7 2BW Tel: 020-75947810 http://www.hep.ph.ic.ac.uk/~dbauer/

directory permissions on the storage

The default on the storage is for the group to have read write but when the directories are created they are created with only read permission. I'm trying to understand if it is a problem with the storage or with the client. The client is dirac either with the commands or with the python API, i.e. j.setOutputData([FILE], outputSE=STORAGE, outputPath=PATH) is there a way to set the permissions correctly? thanks cheers alessandra -- "Annamo a pijà er gelato?"

GridPP DIRAC server upgrade 5. July 2023

******************* This email originates from outside Imperial. Do not click on links and attachments unless you recognise the sender. If you trust the sender, add them to your safe senders list https://spam.ic.ac.uk/SpamConsole/Senders.aspx to disable email stamping for this address. ******************* Dear All, This is an advance warning that we are planning the next major version (v7.3 -> v8.0) upgrade of the GridPP DIRAC instance (https://dirac.gridpp.ac.uk) on Wednesday July 5th. This is necessary to prepare for the x509 to token transition (see [1] if you are interested, but note that this will not impact end users until ~2025) and as the version we are using will go out of support in the foreseeable future. What does this mean for you ? As this is a major upgrade we cannot guarantee that jobs that are in a non-final state will survive, though we will try. If there is something that is very dear to you, you might want to ensure it has finished before we start. The upgrade will proceed in the following order: - Server upgrade - Web interface upgrade - cvmfs UI upgrade - cloud interface (in case of problems only) v8.0 is a python3 only release. No python-2 UIs will be supported. If this poses a problem for you, please let us (or even better the list) know and we will try to help. We have tested the new release version extensively on our various pre-prod servers, so we do not expect any major problems. The upgrade will start at 11:00 am and we expect the server to be back within the hour, but the upgrade of the other components might take longer. We will keep the list updated on our progress. If you are maintaining your own DIRAC UI you will need to upgrade your UI afterwards, as unfortunately for a major release change there is no backwards compatibility. The upgrade procedure will not be significantly different to any previous DIRAC UI installs you may have done. We will supply instructions as usual. Note that you cannot pre-emptively upgrade your UI, so please don't try ;-) Please let me know if you have any questions and/or if this date is the worst possible date for the upgrade we could have picked. Regards, Daniela & Simon [1] https://indico.jlab.org/event/459/contributions/11492/attachments/9358/1399… -- ----------------------------------------------------------- daniela.bauer(a)imperial.ac.uk HEP Group/Physics Dep Imperial College London, SW7 2BW Tel: Working from home, please use email. http://www.hep.ph.ic.ac.uk/~dbauer/

Transferring Directories to DIRAC

If you trust the sender, add them to your safe senders list https://spam.ic.ac.uk/SpamConsole/Senders.aspx to disable email stamping for this address. ******************* Good afternoon, Could you advise me on the best way to transfer a directory to DIRAC? I want to use the neutron cross section library JEFF-3.3 for a simulation I'm running but it's too big to include in the sandbox (~1.9G) when I submit the jobs and is a directory with quite a lot of files so I can't just use dirac-dms-add-file. I've had a quick look on cvmfs and I can't find it available on there as an alternative. Thanks for your help, Kind regards, Jo Orpwood

Minor upgrade of the GridPP DIRAC instance to accommodate AREX

If you trust the sender, add them to your safe senders list https://spam.ic.ac.uk/SpamConsole/Senders.aspx to disable email stamping for this address. ******************* Dear All, There will be a minor version update to the GridPP DIRAC instance tomorrow, Friday 16/12/22. This is so DIRAC can start using the AREX interfaces of the ARC-CEs as the ARC interface DIRAC is currently using is becoming obsolete. Hopefully this upgrade should not interfere with any running/queued jobs and it will require no upgrades on the user side. Having said this, if you notice anything odd after the upgrade, please let us know as soon as possible.

GridPP proxy for Migdal group and production role.

If you trust the sender, add them to your safe senders list https://spam.ic.ac.uk/SpamConsole/Senders.aspx to disable email stamping for this address. ******************* Hello Daniela and Simon, I am a member of GridPP VO. I would like to create a proxy for the Migdal group, with production role. I would like to use this to then register the Migdal files on PPD dCache with the GridPP instance at Imperial. How would I go about creating the Dirac proxy for this? I tried something along the following lines but it did not work. Migdal is not a VO on its own, but is a group within the gridpp VO. dirac-proxy-init -g gridpp.migdal_user -M gridpp:/gridpp/migdal/Role=production -U I am obviously trying to replicate the following voms-proxy-init command within the Dirac environment voms-proxy-init --voms gridpp:/gridpp/migdal/Role=production --valid 168:0 Any help on this would be wonderful! Thanks and Cheers, Raja.

Reminder of planned upgrade Monday 25/07/22

******************* This email originates from outside Imperial. Do not click on links and attachments unless you recognise the sender. If you trust the sender, add them to your safe senders list https://spam.ic.ac.uk/SpamConsole/Senders.aspx to disable email stamping for this address. ******************* Dear All, As announced before, the next major (v7r2 -> v7r3) upgrade of the GridPP DIRAC instance (https://dirac.gridpp.ac.uk) will happen on Monday July 25th. What does this mean for you ? As this is a major upgrade we cannot guarantee that jobs that are in a non-final state will survive, though we will try. You might want to consider leaving your jobs to finish over the weekend and only restart once we announce the completion of the upgrade on this list. The upgrade will proceed in the following order: - Server upgrade - Web interface upgrade - cvmfs UI upgrade - cloud interface (in case of problems only) v7r3 is a python3 release. For backwards compatibility we will maintain a python2 UI on cvmfs as well as a python3 UI. Python 3 will be the default. If you are maintaining your own DIRAC UI you should try to upgrade soon thereafter, though the old UIs will probably keep working for quite a while. The instructions on how to update your UI will be published as usual on: https://www.gridpp.ac.uk/wiki/Quick_Guide_to_Dirac as soon as we have ascertained that the server is stable. We expect the whole process to take a couple of hours, though the cvmfs repos might take a while to sync. We will keep you informed as the upgrade progresses.
