vfstest [-d debuglevel] [-c command] [-l logdir] [-h]
vfstest is a small command line utility that has the ability to test dso samba VFS modules. It gives the user the ability to call the various VFS functions manually and supports cascaded VFS modules.
The higher this value, the more detail will be logged to the log files about the activities of the server. At level 0, only critical errors and serious warnings will be logged. Level 1 is a reasonable level for day-to-day running - it generates a small amount of information about operations carried out.
Levels above 1 will generate considerable amounts of log data, and should only be used when investigating a problem. Levels above 3 are designed for use only by developers and generate HUGE amounts of log data, most of which is extremely cryptic.
Note that specifying this parameter here will override the log level parameter in the smb.conf file.
