Failed! and therefore, mounting did not start and the work never start, the task became a dead longrunner. I found a post https://cernvm.cern.ch/portal/filesystem/debugmount but appearently its not for windows. How can I fix this problem when using a win10 vbox? Many thanks! ID: 41701 · Reply Quote

Most of the time failing CVMFS is caused by a network problem. Be sure you have a continuous stable connection. I agree, that when CVMFS fails, the VM should get a shutdown signal and BOINC should report an error. ID: 41704 · Reply Quote
