Introduction Announcements: new old report cycle: Operations meeting now back to Mondays, accordingly report window will not change as announced in the last meeting. SL4: posted link to talk from Markus Schulz (see agenda). so far 90% of gLite ported to SLC4 to be finished by end of October. Deployment expected before the end of the year. Please start planning for the migration. perhaps start with pps and gather experience with the different dependencies. VOMS: one of the services that will be pushed for towards the end of the year. See also WLCG Commisioning schedule (linked to the agenda page). There are also links on talks concerning the deployment schedule and yaim installation (see agenda page). Job priorities: talk of Jeff T. linked to the agenda page: experiments will use voms roles for sgm and normal users, make sure to have voms configured correctly. Collection of items to be forwarded to the TCG: use this forum to collect and discuss issues to be raised. Horst will gather items and prepares a report on a regular basis Actionitems - Action point: posted network measurement survey -> so far no answers received. please participate ! Open. - communication channels: complicated situation, wants everyone to decide if he wants to receive mails (admin list or personal mail addresses) -> communicate your preferences!Open. - Assessgrid: sites are still encouraged to participate -> they are interested in job traces, hardware information (like CPU temperature, fan speed) and node maintenance cycles. Please participate!Open. - Dech VO: Supported? (Ute has made tests --> to be submitted, nothing much seems to have changed though). Open. - VOs: Clemens still to send list around (!#) -> everything is in the CIC portal, sites see no particular need for a detailed list. Closed. - SFT-Server: installed, Apache, Tomcat and MySQL running, one servlet missing that should listen on port 8088 related to RGMA Server functionality... -> Open. 2. Round the Sites DESY ---- started to setup PPS. again no easy thing. usual problems with missing dependencies. newly installed LFC on PPS not working, Workload manager installation also not straightforward. Production: heavily participating in CMS data challenges. annoyed by changed fetch CRLs for CA certificate updates, lost jobs because of that. Annoyed by hardcoded java version _08 in the m/w. Also opened bug concerning the draining of the RB. Answer was unsatisfactory: blocking port 9002 -> user will see native api error and eventually change rb, which is a bad concept C.K.: this is part of the issues that will be forwarded to the TCG. FZK ---- Experiencing various routing issues, that led to a short network outage and failing rm tests. Fixed RB instability (was out of disk space) planning to update dCache in two weeks time to 1.6.6.6 SCAI ---- heavily involved in biomed data challenge, disc with file system crashed after heavy usage from biomed, no jobs running for some time due to that, problem with biomed licence server experienced the known openssh upgrade problems, lost biomed docking data because of that! biomed will use WMS starting from november trying to produce a glite standalone version for a training course in paris. experienced problems with setting up the WMS, strange thing because of existing working WMS at SCAI itself, related to gLite version 3.0.2? or simply some paths set incorrectly? CSCS ----- no bigger problems. experience the troubles with the openssh update that lead to JS failures. expects new storage delivery and will then change from DPM to dCache, could probably ask for support then cscs heavily involved in cms data challenge with good results would like to use dech VO temporarily for new application: core grid (only one user, probably for December, does not need resources) C.K.: this is also what dech VO was designed for, see no problems with this Dortmund -------- everythings working fine apart from a problem with failing LHCb data transfers. Investigating. Freiburg ------ experiencing some shortage of personel. Peter Wienemann has left. Guenther only available for about half a working day. local VO seem to work fine. some job problems with LHC experiment. investigating ITWM ---- new hardware has arrived, SE extended and new nodes included into the production system informations system experienced heavy load, will be moved next week, SD is planned somewhat surprised that new machines did not need SL4, they are working fine so far under SL3 3. COD Have given feedback at last COD meeting in Geneva: was well received. Integrated various working groups there. Christian was working with Italian team concerning failover. 4. ROC-On-Duty G.G.: There are still quite some old tickets, one should check wether they can be closed. DESY support group now split into two seperate ones: DESY-HH and DESY-ZN. H.S.: no further questions concerning handover AOB --- none
