SAM CMS Software Installation Test

Full name: org.cms.WN-swinst

Maintainer: C. Wissing

Overview

Verifies that the CMSSW versions required by CMS are installed on the site, available through scramv1 and published in BDII

Checks

This script checks:

• that the CMS software directory ($VO_CMS_SW_DIR for gLite/ARC and $OSG_APP/cmssoft/cms for OSG) is defined, exists and is readable
• that the CMS software directory is writable by lcgadmin (only on gLite/ARC, except CERN and sites CVMFS mount /cvmfs/cms.cern.ch)
• that the CMS software initialisation script (cmsset_default.sh) can be sourced without errors
• that scramv1 is found
• that installation is OK for a selected list of releases (so called required CMSSW releases) , by creating a project area with scramv1 project CMSSW CMSSW_X_Y_Z and setting up runtime environment in the project area with eval `scramv1 runtime -sh`
  • the list of required CMSSW release is maintained here in CVS and updated as needed
• that if a production release is installed, the corresponding VO-cms tag is published in BDII lcg-bdii.cern.ch:2170
• that if a production release is published in BDII, it is also installed
  • list of production release is from Tag Collector
  • list of tags published in BDII is in this page (updated every hour by a crontab)
• that architecture tags (like e.g. VO-cms-slc5_amd64_gcc434 and VO-cms-slc5_amd64_gcc462) are published in the BDII
• that all production releases are installed

Troubleshooting

The CMSSW releases are usually maintained centrally by for most of the sites. In case of questions and problems site admins are always welcome to submit a Savannah ticket and assign it to the cmscompinfrasup-cmsswdeploy squad.

WARNING: Some production release is not installed

Cause: The release has not yet been installed.

Note: The deployment cycle of release might need several hours.

Solution: In most cases it is sufficient just to wait until the deployment team has rolled out the missing release.

WARNING: Some CMS VO Tags are missing

Cause: List typical cases when it can occur.

Note: After a new release was announced and installed, it takes some time until information system is up to date.

Solution: The missing tags should be published, or the corresponding CMSSW releases uninstalled. The first option is highly preferred.

WARNING: Cannot write to CMSSW installation area

Cause: the lcgadmin role does not have write permissions on the software area. Software installation via grid jobs is impossible.

Solution: grant write permission in $VO_CMS_SW_DIR (for gLite/ARC) or $OSG_APP/cmssoft/cms (for OSG) to the local user to which the lcgadmin role is mapped.
