       VLLog - Traces Volume Location Server operations


       The VLLog file records a trace of Volume Location (VL) Server (vlserver process)
       operations on the local machine and describes any error conditions it encounters.

       If the VLLog file does not already exist in the /var/log/openafs directory when the VL
       Server starts, the server process creates it and writes initial start-up messages to it.

       The file is in ASCII format. Administrators listed in the /etc/openafs/server/UserList
       file can use the bos getlog command to display its contents. Alternatively, log onto the
       server machine and use a text editor or a file display command such as the UNIX cat
       command. By default, the mode bits on the VLLog file grant the required "r" (read)
       permission to all users.

       The VL Server records operations only as it completes them, and cannot recover from
       failures by reviewing the file. The log contents are useful for administrative evaluation
       of process failures and other problems.

       The VL Server can record messages at several levels of detail. By default, it records only
       very rudimentary messages.  The initial level of detail logged by the VL Server can be set
       by using the -d command line option (possibly multiple times) when it is started.

       To increase the level of detail logged by a running VL Server, issue the following command
       while logged onto the database server machine as the local superuser "root".

          # kill -TSTP <vlserver_pid>

       where <vlserver_pid> is the process ID of the vlserver process, as reported in the output
       from the standard UNIX ps command. To increase to the second and third levels of detail,
       repeat the command.

       To disable logging, issue the following command.

          # kill -HUP <vlserver_pid>

       To decrease the level of logging, first completely disable it and then issue the "kill
       -TSTP" command as many times as necessary to reach the desired level.
