NAME         top

       rpcdebug - set and clear NFS and RPC kernel debug flags

SYNOPSIS         top

       rpcdebug -vh
       rpcdebug -m module
       rpcdebug -m module -s flags...
       rpcdebug -m module -c flags...

DESCRIPTION         top

       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.

OPTIONS         top

       -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.

       -m module
              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.
