Common Issues

cmssw startup

When I try to start the container with cmssw-cc7... I get the following error:

bash: /local/grid/cmssoft/cms/cmsset_default.sh: No such file or directory

The command cmssw-cc7 is simply a bash script that tries to recreate your current environment within a CentOS7 container. This means it will re-source cmsset_default.sh from whichever directory you originally sourced it. The symlink at /local/grid/cmssoft/cms/ simply points to /cvmfs/cms.cern.ch/` however, this means it uses the wrong directory within the container and you see this error.

CVMFS Instability

For some reason, the CVMFS mount is failing to reinitialize after it enters some error states. This causes some machines to occasionally lose access to CVMFS. You can check if CVMFS is available by running the following command. If CVMFS is operational on that machine, you will see a long list of different software options provided by CVMFS.

ls /cvmfs/cms.cern.ch
