rpcdebug(8) System Manager's Manual rpcdebug(8)
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.
FILES
/proc/sys/sunrpc/{rpc,nfs,nfsd,nlm}_debug
procfs-based interface to kernel debug flags.
