Diagnoses - Actions

If the service is failing on an specific site, the first thing is to go to dashboard and check the SUM/CE tests

Select the metric

org.cms.WN-swinst

And select the server showing problems. A full report of the tests will show-up. Some information on it might be usefull to guide the analysis work.

Some of the main reasons for failure are:

Bad installed or not yet deployed release of CMSSW

To discover if a release of CMSSW is allready installed on the deployment server and available to use

* log in lxplus * cd /cvmfs/cms.cern.ch/ (the final slash "/' is essential) * cd slcX_Y_Z * cd cms/cmssw (full versions) or cms/cmssw-patch (patch releases) * ls

If the desired release is showing then it was allready published. However it may be not working. To test, try installing it on lxplus

  • source /mnt/cvmfs/cms/cmsset_default.csh
  • SCRAM_ARCH=slcX_Y_Z
  • cmsrel
  • cd /src
  • cmsenv

On the first time that a release is installed as above, only the directory names will show, but they will be empty. This is normal. Try running something

  • runTheMatrix.py -s > & rtm.log &
  • tail rtm.log

If the tests fail then there is a problem with the release, open a Savannah ticket to cmscompinfrasup-cvmfs

Failure on release servers

There are 5 stratum-1 level servers delivering the CMSSW releases. The status page can be found at

https://sls.cern.ch/sls/service.php?id=CVMFS_Stratum1_cms

If a server is degraded it should not be a major problem, since the others will take its work.

Observations

  • SLC6 versions are still not supported
  • The versions of SLC5_ia32_gcc434 are installed but not working, due to architecture changes. They are kept only for historic reasons
