HP CIFS Server Administrator Guide Version A.02.04.04 (5070-6710, October 2011)

-k Disables the CFSM tracing.
-l <level> Sets the CFSM trace level. The minimum is 0, the maximum is 8. Setting
to 0 corresponds to no tracing. The default level is 0. Trace level 1
corresponds to minimal tracing, only crucial, major events are logged.
Trace level 8 corresponds to maximum tracing.
-f <filename> Sets the trace filename. The default is /var/opt/samba/log/
cfsmtrace.log.
-m <filemaxsize> Sets maximum size of the trace file in megabytes. The defaults value is
1.
NOTE: To use the —m option, you must disable CFSM tracing.
-h Displays help text.
For detailed information on how to use this command, refer to the cfsmutil man page.
The trace level, tracing log file name and maximum tracing log file size settings are all persistent
across reboots.
The trace messages may be useful to understand the actions CFSM takes to enforce the CIFS client
file locks, and HP support engineers may need this data to diagnose problems. However, enabling
CFSM tracing will greatly reduce the performance of any file system using CFSM. Hence, it is best
to leave tracing turned off, unless it is needed to diagnose a suspected problem.
NOTE: The CFSM trace level setting is persistent across reboots. If the CFSM trace level is non-zero
when CFSM is loaded, then tracing will automatically be turned on. This allows trace messages
to be logged while file systems are mounted at boot time. Therefore the trace level should be kept
at 0, otherwise tracing will be automatically turned on when booting the system.
