You're not running NFS version 3, but running version 2.
I presume you're taking that from the "nfs" lines above?
while rpcinfo on the client (KnoppMyth) says:
program vers proto port
100000 2 tcp 111 portmapper
100000 2 udp 111 portmapper
100021 1 udp 32768 nlockmgr
100021 3 udp 32768 nlockmgr
100021 4 udp 32768 nlockmgr
100021 1 tcp 36516 nlockmgr
100021 3 tcp 36516 nlockmgr
100021 4 tcp 36516 nlockmgr
On your client side, you don't have support for NFS version 2.
Here I presume you're looking at the "nlockmgr" lines.
I've googled and checked man pages, but I can't find any
discussion of NFS version and compatibility issues. Are
my two boxes incompatible? (I hope not - it would be a
surprising and disappointing departure from the high degree
of compatibility I've come to take for granted from Linux,
and TCP/IP in general.)
Where do I go from here? Do I have to install another version of
Linux on one or both boxes? Do I have to find modules and rebuild
one or both kernels? Or are there some undocumented parameters I
have to tweak? (Charlie's First Law of Documentation states that
if you can't find it in the documentation, it isn't documented.)
