It's possible to get a dump of the RPC task queue by writing a value to
/proc/sys/sunrpc/rpc_debug. If you write any value to that file, you get
a dump of the RPC client task list into the log buffer. This is a rather
inconvenient interface however, and makes it hard to get immediate info
about the task queue.
Add a new directory hierarchy under debugfs:
sunrpc/
rpc_clnt/
<clientid>/
Within each clientid directory we create a new "tasks" file that will
dump info similar to what shows up in the log buffer, but with a few
small differences -- we avoid printing raw kernel addresses in favor of
symbolic names and the XID is also displayed.

Choose Y here to enable Secure RPC using the Kerberos version 5
|
|
GSS-API mechanism (RFC 1964).
|
|
|
|
Secure RPC calls with Kerberos require an auxiliary user-space
|
|
daemon which may be found in the Linux nfs-utils package
|
|
available from http://linux-nfs.org/. In addition, user-space
|
|
Kerberos support should be installed.

If unsure, say Y.

help
|

This option enables a sysctl-based debugging interface
|
|
that is be used by the 'rpcdebug' utility to turn on or off
|
|
logging of different aspects of the kernel RPC activity.
|
|
|
|
Disabling this option will make your kernel slightly smaller,
|
|
but makes troubleshooting NFS issues significantly harder.
|
|
|

If unsure, say Y.
