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. If there is an existing file,
the VL Server renames it to VLLog.old, overwriting the existing
VLLog.old file if it exists.
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
The VL Server can record messages at three levels of detail. By
default, it records only very rudimentary messages. To increase logging
to the first level of detail, 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
UserList(5), bos_getlog(8), vlserver(8)
