SEE ALSO

BUGS

The default output has be changed. To get the old default output you must run nfsstat --auto -2.

The function of the -v and -a options have changed. The -a option is now reserved for future use. The -v does what the -a option used to do, and the new -[234] options replace the -v option.

The Display section should be more complete.

Further bugs can be found or reported at http://nfs.sf.net/.
