NAME

6       rpcdebug - set and clear NFS and RPC kernel debug flags
7

SYNOPSIS

9       rpcdebug -vh
10       rpcdebug -m module
11       rpcdebug -m module -s flags...
12       rpcdebug -m module -c flags...
13

DESCRIPTION

15       The rpcdebug command allows an administrator to set and clear the Linux
16       kernel's NFS client and server debug flags.  Setting these flags causes
17       the kernel to emit messages to the system log in response to NFS activ‐
18       ity; this is typically useful when debugging NFS problems.
19
20       The first form in the synopsis can be used to list all available  debug
21       flags.   The  second  form  shows the currently set debug flags for the
22       given module.  The third form sets one or more flags,  and  the  fourth
23       form clears one or more flags.
24
25       The  value  all may be used to set or clear all the flags for the given
26       module.
