This tool is part of the Samba(7) suite.
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.
Execute the specified (colon-separated) commands. See below for the commands that are available.
debuglevel is an integer from 0 to 10. The default value if this parameter is not specified is zero.
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(5) file.
Print a summary of command line options.
File name for log/debug files. The extension
'.client' will be appended. The log file is never removed
by the client.
