0. Welcome to Sabah who's now joining the list. Next meeting
is 9 March.
1. Review of Actions
Can people outside get write access to storage web site Jens Open
-- Andrew says PPD runs a web server serving pages from AFS.
-- For now, send stuff to me (Jens) and I will happily upload it,
or to Owen and he will patch his documentation.
-- Need for CVS in the longer term.
Can Edinburgh provide bugzilla? Phil Open
-- Part of the same question. Not likely to happen soon.
Can we use the helpdesk? Jens Closed
-- Short answer is no. It will cost a lot of money in extra
licenses (for people). It *is* possible to add storage to
the helpdesk though.
Send external URLs to Jens ALL Open
-- Ongoing.
Update project page to point to new storage web site Jens Closed
-- Done.
Figure out why dCache doesn't use DCAP Jiri Closed
-- Done. Documentation to appear on web.
Send report on data transfers to list Steve Open
-- Still open. Some work may need to be redone.
Resurrect SRM client API Jens Open
-- There is an API but it requires fairly intimate knowledge of
gSOAP and the SRM protocol. Writing a good simple API not
likely to happen soon with other workload, particularly a
C one. C++ or Perl might be easier.
Plan for Tier 2 deployments Jens Closed
-- There is a plan, agreed with Jeremy and the T2 coordinators.
Hasn't been implemented yet though, waiting for
all-other-Tier-2s-than-Edinburgh to catch up. Alessandra
is saying she expects to start this week.
Send DPM endpoint to Jens for interop testing Andrew Open
-- This is Andrew Smith. He has been busy with LHCb tools,
nothing much has happened on the DPM front.
Update docs to include lcg-* Jens Open
-- Still open. More general client documentation to appear.
2. Tier 2 rollout status.
See above. Waiting for everyone-but-Edinburgh to catch up...
3. dCache experiences.
Much captured by useful thread on list (quod videt). Andrew (Sansum)
reports dCache is now operational again, seeing 60 MB/s to disk.
Database moved off head node, now seeing 10-20% load on head and
about 40% on database. Speculating that database is spending lots
of time on inefficient queries [/me or needs vacuuming]
Need to agree with CMS whether they will start to write to tape
soon. Or we can restart the tape tests.
4. DPM status.
No news; see above.
5. Client tools.
See above - we have an API but it's not easy to use. Writing
experimental CLI advisoryDelete. Although we do not officially
support client side tools, we have a lot of experience with them
and need to make this available on the web.
6. AOB
Who's going to GGF13? Apparently no-one. We expect it's Arie's
turn (of the Arie/Peter duumvirate) to go. Owen points out that
there are other storage-relevant areas in GGF [meaning GFS-WG].
More importantly, is there an SRM workshop planned? None known,
but best to check with Arie.
NEW ACTIONS:
Can GFAL be preloaded Jiri Open
-- From quick tests, GFAL does not appear to pass local files
through to kernel open. GFAL does not provide gfal_fopen
either. Thus it might be necessary to preload another
library that maps open to gfal_open. Test plan agreed.
Contact James or J-P about DPM source Jens Open
-- Phil points out we should get the source from the source,
so to speak.
Contact Arie about next SRM workshop Jens Open
-- I'll volunteer to do that.
