(k)ubuntu NFS buy

[Jim Anderson]

Hi,

I'm having a problem with NFS using Linux Kubuntu 10.10. I have logged 
my problem at the Kubuntu 10.10 forum and thus far I have had no 
response. Since Kubuntu/Debian package NFS with their release, it does 
not surprise me that I have had no response as yet.

I was thinking and realised that I probably need help from the 
developers. My problem seems like it is due to a bug in NFS, although it 
could easily be something wrong with my environment or the packaging. I 
did see some similar problems on the net with Red Hat.

Anyway, below is my write up from the Kubuntu forum.

Can you tell my problem is a known bug with NFS?

I'm running a home network and I used NFS to share files between the 
Linux PCs. Everything was working fine
until 2 days ago, when I started getting error messages that I could not 
store files on remote servers. I tried
rebooting and mounting a file system from the server and I got the 
following message:

mount.nfs: requested NFS version or transport protocol is not supported

The client is running Kubuntu 10.10 with NFS 1:1.2.2-1Ubuntue1.1. The 
server is running NFS 1:1.2.0-2. The older
version is not that old and I was surprised at the apparent 
incompatibility that suddenly appeared. Rather that
try to figure out what was in compatible, I decided to upgrade the 
server to Kubuntu 10.10 so that the NFS
versions are identical. After installing NFS on the server, I am still 
getting the same error message.

I did a search on the error message and I found the following Ubuntu 
bug: https://bugs.launchpad.net/ubuntu/+source/nfs-utils/+bug/656889
According to this bug report, This is a bug and it is not fixed in 10.10 
final release.

Do I move onto Kubuntu 11.04 or back to Kubuntu 10.04?

That's unlikely to be your problem since your server does support tcp.  But
maybe you have a firewall problem.  Try proto=udp and nfsvers=3 mount
options (separately).  If proto=udp works, fix your firewall.

Jim,

Thank you for the suggestions. If I understood right, I should try:

 >>> mount -t nfs duke:/mnt/myFiles /mnt/myFiles -O proto=udp

and

 >>> mount -t nfs duke:/mnt/myFiles /mnt/myFiles -O nfsvers=3


I tried both of these to mount the NFS files and got the same error message.

I'm not sure what that will do but I don't think it's what you want.  Try
these:

mount -o proto=udp duke:/mnt/myFiles /mnt/myFiles
mount -o nfsvers=3 duke:/mnt/myFiles /mnt/myFiles

Thanks again for the suggestions. I'm not sure what solution would work, 
if anything, but my problem is fixed.

I upgraded all of my systems to Kubuntu 10.10 and NFS is working again.
I assume there is some type of compatibility bug, but it is not work
tracing the root problem now. This took a bit of time, but it is 
probably for the better that the other systems are all upgraded now.
