Please read NEW in knfsd-980922. You need to update your rc.nfsd.

Please give it a try.

Thanks.

This is the Linux kernel NFS daemon. It is based on linux-nfs 0.4.22.
It is tested on Linux/alpha and Linux/x86 running glibc 2.0.7.


Changes from knfsd-980920:


1. Add NFS mount version flags to mountd. Change rc.nfsd to disable
   NFS V3 for mountd.
2. Fix client hostname.
3. rc.nfsd runs kexportfs with -r instead of -a for restart and reload.


Changes from knfsd-980915:


1. There is a knsfd quota patch for Linux 2.1.1xx, quota-2.1.1xx.diff.
   It is only tested on linux 2.1.122.
2. The submount pathname is removed from the xtab file.
3. rc.nfsd runs kexportfs with -r instead of -a for start.
4. Fix kshowmount -e.
5. Fix hostname matching.
6. Fix compiling on libc 5.


Changes from knfsd-980910:


1. nfsd-2.1.121-3.patch from G. Allen Morris III (gam3@acm.org).
2. A new flag, -r, for exportfs.
3. Don't put an entry in xtab if kernel rejects it.
4. Use the official hostname when checking if 2 hostnames are the same.
5. Allow submounts.

You have to apply the patch, linux-2.1.1xx.diff, to the Linux kernel
first. It fixes quite a few nfs bugs. That patch is against Linux
2.1.111. If your kernel is different, you have to apply it by hand.


If you want quota to work for knfsd, you also need to apply the patch, 
quota-2.1.1xx.diff, to the Linux kernel. This patch is against Linux
2.1.122. If your kernel is different, you have to apply it by hand.


nfsd-2.1.121-3.patch is another knfsd patch against linux 2.1.121 by
"G. Allen Morris III" (gam3@acm.org). It works for me on x86 and alpha.


To compile, just do


# make


Makefile will try to determine which C library you are using and compile
this package accordingly.


# make install


will install the knfsd binaries. You have to install a knfs start up
script by hand. There is a new rc.nfsd in etc. I use it for both the
user-space nfsd and the kernel nfsd.


The NFS lock is only tested with knfsd. If the NFS lock doesn't work
for you, please try knfsd first before reporting it.


Thanks.
