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 :)

Jan: Working on web-admin

Paul: gPlazma, tickets

Tigran: nothing special

Irina: working with ACL srm ticket; tape protection issues reported by PIC

Antja: Tickets, better ways of following the tickets; QA

Tanja: tickets, NFS learning 4.1 and implementing "stuff"

Thomas: Wandering sub-actic swamps in Sweden.

Timur: Most of time working on gPlazma :-)

Owen: glue between site-layout and site-info.def MVCs. Currently trying to get certificate testbed suites in LCG data-management tools working. Copying with final issues with migration of server consolidation using Xen.

Plans for patch-releases

Should we make a new patch release?

Tape protections for 1.9.5

Maybe.

Billing

CDF experiment want to better leverage information from the billing database. Records in different ... Currently impossible to tell which transfer triggers activity in PoolManager.

BillingInfo? table stores information from pools.

DoorInfo? about requests.

StorageInfo? which is stores and restores from tape: info actually comes from pools.

Users want to know which door triggers staging of file from tape.

Staging is triggered internally in the state-machine, not by

PoolManager would need to be changed so the state machine entry would keep track of which request it is handling.

Trunk activity

Progress with new features...

gPlazma

Timur: implemented strategies.

gPlazma library itself and second is the cell.

PluginLoader? is now written.

Current TRUNK gPlazma continue to work.

What plugins are needed?

Tigran has a NIS server plugin, but it needs some work. Supports map and reverse-map but implementation is ugly so not on ReviewBoard yet.

Need the create-new-UID although this requires additional infrastruction: the map and reverse-map calls to gPlazma.

We can create a dCache setup that has unique IDs for user with current support; therefore we should first add support for map and reverse-map calls and update components to use them.

1.9.9 release process

15th of June is cutoff for patches going into 1.9.9.

extension to layouts

When doing automatic configuration of dCache cluster. There's an issue commenting out a service or a domain, due to not having an end-of-block marker.

Noone objects to including an "enabled" property to disable a service; although it was felt that this is a move away from the idea of services is enabled by being defined.

nothing can be fixed for 1.9.9

Further discussion on whether to switch to a different format.
