Failed to connect slave due to missing folder on the master

    XMLWordPrintable

Details

    Description

      We have a JNLP slave which failed to connect.
      On the slave side there was something about a connection reset as error.

      On the server side we found this in the log:

      Feb 5, 2013 9:36:44 AM hudson.TcpSlaveAgentListener$ConnectionHandler run

      It appeared to be that the folder /opt/jenkins_home/logs/slaves/srv-nl-crd62 did not exist.
      After creating the folder, the slave could connect.

            No response to comment asking for updated information in 2.5 months, so resolving as Incomplete.

            AFAIR various logs were moved from JENKINS_HOME to subdirectory. Is it still reproducible?

            Can this be reproduced on recent versions of Jenkins? Quite a bit was changed in JNLP slave handling, so I'm not sure how relevant this report still is to current Jenkins.

            No, we did change anything to the logging. All other slaves (80+) were working fine.
            The master is a linux machine, the slave is a windows machine.
            The error is in the logfile of the master, and is complaining about a location on the master.

            Do you redirect log directory outside the slave's workspace (opt/jenkins_home/logs/slaves/srv-nl-crd62/slave.log)? If yes, then behavior is predictable. Jenkins creates folders tree only for workspace.

            Try update jenkins version?
