NAME

       rpcdebug - set and clear NFS and RPC kernel debug flags

SYNOPSIS

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

DESCRIPTION

       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

       -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.
