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.
