          SRM Update 10m
          Speaker: H.Renshall
          Following the release of dcache 1.8 patch level 21, this was installed at the Tier-1 srm 2 testing dcache sites apart from NDGF. Unfortunately it exposed configuration problems and new bugs so essentially all dcache sites except NDGF were unavailable for experiment tests this past week. The developers have now released patches 22 and 23. Patch 23 has been tested at DESY by doing a fresh install and found to fix the patch 21 problems but exposed a new one with gridftp. This has been reported and followed up with the developers. The gridftp problem was due to a configuration problem that was solved. Therefore, dCache 1.8-23 has been released to sites to install. Yesterday we had a CERN Oracle problem not understood that was cured by restarting the database service. The problem has been escalated to Oracle support. At CNAF, CASTOR became unavailable yesterday and the reasons are not yet clear. CASTOR at CNAF has hardly been used by the experiments because of its high instability/unavailability. STORM has been working very well. RAL intends to make available its SRM v2.2 test instance for LHCb tests with SRM v2.2. RAL will be tested today or tomorrow by Flavia to make sure it is well configured for LHCb. ATLAS has been exercising transfers but without space tokens. ATLAS will now pause testing till after their M5 detector cosmics run ends on 5 November. We have not yet tried CASTOR at CERN as a source with SRM 2.2 but this is now planned for next week. LHCb are ready for this now but need external sites.

          CCRC Update 10m
          Speaker: H.Renshall
          There was a planning meeting on Oct 22nd. The agenda and attached documents are at: http://indico.cern.ch/conferenceDisplay.py?confId=22668 - LHCB (N.Brook): Presented their CCRC'08 targets table. The Feb. to May data volume difference is because the May run has two extra weeks. Same rates but since it runs twice as long there is twice the data. The CCRC LHCb data can be scratched. - Atlas and Alice have yet to submit their targets but Alice (L.Betev) will do so by the end of this week. Alice emphasised they will be using their normal production resources as required for p-p running. - Atlas representative did not attend the meeting as he was involved in FDR planning during the current Atlas week so we expect input soon. - CMS (M.Kasemann) will use mixed mock and cosmics data. CMS knows how to separate these data at the SE level so that mock data can be dropped. - F.Donno will present next week the storage resource requirements being gathered from the experiments. - H.Renshall pointed out a clarification email from Alice that Alice does not require SLC4 WMS and can run with SLC3. - PIC questioned LFC deployment for LHCB. Although 3D streams are being replicated to PIC there is no LFC front-end deployed. They asked if they should deploy the current version or the next version where UID/GID is also replicated from CERN ? N.Brook will check but first answer is that PIC should wait. - H.Renshall reviewed the delivery schedule of the explict software requirements. An unknown is that for the fully functional glexec - see later talk of J.Gordon. R.Trompert pointed out that NL-T1 has now announced Nov 19 as the date for it's dcache 1.8 migration. - A.Aimar presented his first draft of the ccrc'08 milestones and is now awaiting reactions from sites and experiments. - Next week ATLAS and CMS will be visiting ASGC.
