CREAM Certification HOWTOs

Known Issues

  • lcg-info-dynamic-software-1.0.5-1 introduce tuti i vecchi bug, te cui 59871)
  • da verificare nel prossimo update (1.14.2) la presenza di lcg-info-dynamic-software >1.0.5-1 e diverso da 1.0.7-2
  • Sometimes the "Automatic job purge" test, running inside the testsuite, fails with the error "CATALINA_HOME must be set!". In the same time, the test launched stand alone does not fail. To fix this problem check and fix JAVA_LOCATION in the site-info.def used to configure the cream ce under test, if needed re-run yaim.

Preliminary checks befor to run CREAM and BLAH testsuites

  • Check that the right CE (ce to test) is well configured in
    • /opt/cream_test/lib/vars.py
      In this file pay expecially attention to:
      • lfc_host
      • lcg_gfal_infosys they can be empty but the test outputdata fails if they are not configured
    • /opt/cream_blah_testsuites/lib/conf/cream_testsuite_conf.ini
      In this file pay expecially attention to:
      • EMI version
      • tomcat version
      • blparser version and consequent blparser log value
      • number of CPU in the cluster (needed to saturate the batch system in some test of blah)
  • Check if a simple submission is working (you can use an UI command or the testsuite directly):
    pybot -i simple /opt/cream_test/testsuite/cream_test_suite.html
  • Check if the ssh passwordless from UI to CE is well configured. You can do it trying a ssh command or using the testsuite:
    pybot -i ban  /opt/cream_test/testsuite/cream_test_suite.html

CREAM Regression tests notes

  • Using blah_testing and blah regression testsuites pay attention to two things:
    • Set the right value for parser_log_file parameter in /opt/cream_blah_testsuites/lib/conf/cream_testsuite_conf.ini [if it is not correctly set some tests fail. Need improve to have a message suggesting the problem]
    • Check that in yaim configuration files defined in /opt/cream_blah_testsuites/lib/conf/cream_testsuite_conf.ini it is the right value for BLPARSER_WITH_UPDATER_NOTIFIER, i.e. you are declaring the right blparser (new or old)

  • bugs 83592 and 83593 are fixed only in CREAM EMI 2 in conjunction with emi-UI EMI 2.

CREAM + SLURM notes

  • detagli importanti nel primo task di certificazione IGIRTC-164
  • recipe_slurm.txt: recipe_slurm.txt
  • IMPORTANT:
    • In case you decided to exploit a shared file system, AFTER EACH UPDATE, edit the BLAH configuration file (/etc/blah.config) and add the blah_shared_directories parameter (N.B: the YAIM reconfiguration and the update of the glite-ce-blahp module don't preserve this manual modification) and restart gLite services:
            # echo "blah_shared_directories=/home:/var/cream_sandbox" >> /etc/blah.config
            # service gLite restart 
            
    • In case of SHARED FS - pay attention on NFS mounting on WNs, in /etc/fstab, have something like:
            cert-08:/home /home   nfs   vers=3,timeo=14,intr   0 0
            cert-08:/var/cream_sandbox /var/cream_sandbox   nfs   vers=3,timeo=14,intr   0 0
            
    • slurmdbd PID file - configure it to a directory where user _slurm_can write:
            # grep -i pidfile /etc/slurm/slurmdbd.conf
            PidFile=/var/tmp/slurmdbd.pid
