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.
