Participants

Paul, Tigran, Karsten, Al, Gerd

Agenda

[see box on the right-hand side]

Postcards

Up to two minutes (uninterrupted) per person where they can answer two questions:

  • What I did last week (since the last meeting),
  • What I plan to do in the next week.

No questions until we get through everyone :)

Karsten: Workshop preparation, SmallFiles? Al: Moved office, posted RemplicaManager? patches, and Alarms, setting up VMs for Debug session, worked on document for Replica Manager Dmitry: tested NFS and it seems to be working. Worked on some tickets. Worked on enstore and dCache issues. Gerd: Updated release notes for 2.9 Paul: Tier1 meetings, focused on 2.9 release Tigran: Mostly working on working on Monitoring System and Scripts at DESY

Plans for patch-releases

Should we make a new patch release?

Our test system recently failed because of a sha-2 certificate (S2/G2) -> Therefore upgraded it to use EPEL versions, but then some clients failed when using dCache.org CA issued certificates. Because of that, upgraded the release machines to use "proper" certificates, but that needed the S2 tests to be rebuild which gave other errors. The cause apparently is a bug inside the S2 libraries. -> fixed the S2 tests. Until this is fixed for everything, we cannot do more releases.

Trunk activity

Progress with new features...

HTTP 3rd party transfers

What is the status of the 3rd party HTTP transfer feature?

  • We have a working client that is using apache commons client. This is in test, but currently stalled because of the S2 problems.

Is it integrated with the transfer manager?

  • Yes

Issues from [FIXME: Add link to yesterday's Tier-1 meeting]

We had a lot of people connecting.

Thursday: Simon mentioned they have Webdav in production for selected people. -> will backport filehopping fix

Tuesday: Some more people connected (e.g., NDGF) KIT reports "dcache dump heap" does not work anymore, and apparently the statistics does not scale too well with a lot of files. -> We would need a way to calculate the statistics with any number of files. -> We could use Quartz to have the pools to create a file with a report. For this the Universal Spring cell could implement some API that can then be used to periodically generate a report. This might also be worth to use in other places in dCache as we currently have many differnt approaches

Marc: The Admin Service (ssh2) stops listening after some time.

This is caused by missing file descriptors, because they are not released.

Ivan: IN2P3 asked for help on the NFS+Kerberos issue. NFS+enstore seems to work now, we can merge.
