[gentoo-user] nfs warning: mount version older than kernel

[gentoo-user] nfs warning: mount version older than kernel

[Mark Knecht]

Hi,
   After months of working really well I've just recently started
having trouble with our MythTV setup. I'm looking into what's gone
wrong. The symptom is that recordings periodically look like you're
hitting fast forward. Both audio and video are messed up in the same
way. All machines are Gentoo 32-bit.

   The setup is like this:

- dragonfly - the Myth backend machine has two PVR capture cards in
it. Running on the system is mythbackend, mysql and the ivtv driver
for the cards. This machine is my wife's desktop box and is updated
regularly. I'm seeing various ivtv messages all of a sudden, along
with a specific NFS message:

nfs warning: mount version older than kernel

The kernel is getting a bit old now. Emerge world happens often on this box.
dragonfly ~ # uname -a
Linux dragonfly 2.6.12-gentoo-r6 #3 Thu Aug 4 06:43:20 PDT 2005 i686
Intel(R) Pentium(R) 4 CPU 3.00GHz GenuineIntel GNU/Linux
dragonfly ~ #

- myth14 - this is actually a Myth frontend only machine, but it has a
large disk and serves as the main storage for our recordings. This
machine hasn't been updated in at least 45 days. I see no messages or
problems on this machine.

myth14 ~ # uname -a
Linux myth14 2.6.12-gentoo-r6 #2 Tue Aug 2 16:31:31 PDT 2005 i686
Intel(R) Celeron(R) CPU 2.26GHz GenuineIntel GNU/Linux
myth14 ~ #

   The two machines are hooked together via wired Ethernet going to a
DLink switch. These machines have been in this configuration for
roughly 2-3 months and have worked great until recently when this
problem started.

   Does anyone know what the message above mean and is it telling me
there's a real problem here, or is it truly just a warning and I
should look somewhere else for a solution to this Myth problem?

Thanks,
Mark

What versions of nfs-utils are installed on the systems?

Sorry. I printed that here in a terminal and the forgot to copy it
into the first message. 1.06-r6 on both systems:

dragonfly ~ # emerge -pv nfs-utils

These are the packages that I would merge, in order:

Calculating dependencies ...done!
[ebuild   R   ] net-fs/nfs-utils-1.0.6-r6  +tcpd 0 kB

Total size of downloads: 0 kB
dragonfly ~ #
 myth14 ~ # emerge -pv nfs-utils

first, make sure portmap is running on both machines. I'm sure it is but 
check anyhow. Also make sure they are not wildly different versions. Do 
the same for util-linux package.

run 'rpcinfo -p' on each machine and copy/paste the output. I have a 
feeling one kernel has NFS v3 and another has NFS v4...

Will do. portmap is running on both machines but neither machine has
rcpinfo. What package do I emerge?

dragonfly ~ # rcpinfo -p
-bash: rcpinfo: command not found
dragonfly ~ # slocate rcpinfo
dragonfly ~ #

Thanks much,
Mark

Re: [gentoo-user] nfs warning: mount version older than kernel

[Bryan Whitehead]

you don't have rpcinfo? that is not right!

epm -qf /usr/sbin/rpcinfo
glibc-2.3.5-r1

it should be in /usr/sbin/

maybe you need to rebuild glibc?

rpcinfo will ask your portmapper what versions/protocols your mountd, 
nfs, etc are running as. I don't understand why you don't have this 
command... that is wierd.

Hold on guys, notice the spelling difference - rpcinfo which is what you
need, but rcpinfo is what was searched for.

Re: [gentoo-user] nfs warning: mount version older than kernel

[Bryan Whitehead]

Just to clarify, you can mount right? if so cat /proc/mounts on both 
machines.

can you show me the /etc/exports of the server?

If you are able to mount you should be able to ignore the error. It looks 
like everything is setup ok... unless you have firewall/iptables in the 
way of any packets...

Re: [gentoo-user] nfs warning: mount version older than kernel

[Mark Knecht]

Bryan,
   Yes, I can mount just fine. I was jsut concerned that the warning
was there and since I'm having trouble with
bandwidth/throughput/something I was looking to make it as clean as I
can.

   If this is not an issue I'll ignore it for now. I think my other
thread about 'Lots of network collisions' is going to turn out to be
the real issue. In the short term I'll record locally until I get NFS
working a bit better.

thanks,
Mark

thanks,
Mark
