Grid Operator Hand Over on Duty

  c-COD Team
From ROC IT
To ROC France

Report from cCOD:

  • As last week, there are two tickets regarding APEL problems on two AP sites, opened since more than a month: only in one of them there are some progress, however I will rise both at the WLCG meeting

  1. ROC_SW today has an expired ticket (UPV-GRyCAP), as ROC_DECH (SWITCH)
  2. ROC_SE has a ticket opened a month ago (TR-04-ERCIYES) but non yet solved, expiring today (2nd level of escalation)

  • WLCG items:

  1. Site MY-MIMOS-GC-01 (AP) has still a ticket GGUS:51229 opened a month ago: no feedback by site-admins, only by the AP roc-managers three days ago, after a reminder sent Sep 30th: "sorry for the late, we have some problem dealing with bouncycastle bcprov.jar, we're working on it now as being stuck due to the series of event recently. before the ticket open, we don't read the same error with Taiwan-LCG2 accounting publishing, as well as rgma client check. keep you posted then."

  • Answer from AP ROC: We are dealing with the issue. We are waiting for the site admin to negotiate to open ports for the MON box.

Sites Considered For Suspension

PPS Reports and Issues

  • Update of the Pilot service of Cream CE:
    • CMS is testing the WMS-based submission to CREAM CES at CERN, CNAF, FZK and RAL
    • The tests so far haven't shown any performance limitation in ICE, the upgrade to the latest version, released with gLite 3.1 Update 55 is however recommended
    • A known issue in CREAM, reported with BUG:52651 "CREAM file descriptor overuse" was hit at CNAF

gLite Release News

  • Soon in production: CREAM 1.5
    • it is the version removed because of the security issue. Expect the patch 3259 will go to production soon, within days.

Pierre (ROC_FR): What is the problem of file descriptors with CREAM? Is it the usual problem with inode? Antonio: Probably. It has not been seen by Alice, but it can be seen when using ICE. As soon as CMS started using CREAM it showed up.

EGEE Items From ROC Reports

  • Pierre (ROC_FR): there was a problem with the report, as I had put a problem, which did not appear. Problem with SAM SFT job. Jobs are submitted to the short queue, but jobs are killed as they consume too much CPU. OPS was removed from our short queue.SAM tests should put requirements.
Steve: submit a GGUS ticket, probably the requirement needs to be changed.

  • ROC_FR: dcache was move to chimera. Move successful.

  • Helene: they were problems this morning with the ROC reports. Now the summary of the ROC reports is available again.

Grid Service Interventions

  • Consult links on the agenda page.

Miscellaneous

  • REMINDER: Security vulnerabilities. Last month several alerts were sent to all sites about critical security vulnerabilities in the Linux kernel (CVE-2009-2692 and CVE-2009-2698). o a number of sites still have not upgraded o the EGEE PMB agreed to suspend the vulnerable sites (but they will be warned in advance) o all sites having questions/issues should contact their ROC security contact

  • ROC_DECH: we will have our last site patched by October 12th.

  • REMINDER: Reminder for sites to move to WMS 3.2 (available in gLite repository). This must be done by the end of October!

AOB

  • 2 set of SAM tests are now entering the validation period. ROCs are encouraged to look at them. Report back if there are problems. The tests are
    • MPI tests.
    • CREAM CE tests. results are available from the validation pages

https://sam-val.cern.ch:8443/sam/sam.py?CREAMCE_ops_disp_tests=CREAMCE-sft-brokerinfo&CREAMCE_ops_disp_tests=CREAMCE-sft-caver&CREAMCE_ops_disp_tests=CREAMCE-sft-csh&CREAMCE_ops_disp_tests=CREAMCE-sft-djs&CREAMCE_ops_disp_tests=CREAMCE-sft-job&CREAMCE_ops_disp_tests=CREAMCE-sft-lcg-rm&CREAMCE_ops_disp_tests=CREAMCE-sft-softver&setdefs=on&order=NodeName&funct=ShowSensorTests&disp_status=na&disp_status=ok&disp_status=info&disp_status=note&disp_status=warn&disp_status=error&disp_status=crit&disp_status=maint

The tests results look identical to the LCG-CE ones.

Pierre: will they become critical? Steve: yes, in time they will become critical, after ROC managers approval.
