rpcdebug


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 activ-
       ity; 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.
