       The  rpcdebug  command  allows an administrator to set and clear the Linux kernel's NFS client and server
       debug flags.  Setting these flags causes the kernel to emit messages to the system log in response to NFS
       activity; this is typically useful when debugging NFS problems.

       The first form in the synopsis can be used to list all available debug flags.  The second form shows  the
       currently  set  debug  flags for the given module.  The third form sets one or more flags, and the fourth
       form clears one or more flags.

       The value all may be used to set or clear all the flags for the given module.

              procfs-based interface to kernel debug flags.

-c     Clear the given debug flags.

       -h     Print a help message and exit.  When combined with the -v option, also prints the available  debug
              flags.

       -mmodule
              Specify which module's flags to set or clear.  Available modules are:

              nfsd   The NFS server.

              nfs    The NFS client.

              nlm    The Network Lock Manager, in either an NFS client or server.

              rpc    The Remote Procedure Call module, in either an NFS client or server.

       -s     Set the given debug flags.

       -v     Increase the verbosity of rpcdebug's output.

rpc.nfsd(8), nfs(5), syslogd(8).
