Hi !
I have an Fedora core 4 exporting a directory. It have 2.6.13 kernel.
I mount it on Red Hat Enterprise Linux AS release 3 with 2.4.21-4.ELsmp
kernel. In the server, I get "svc: unknown version (0)" everytime. In
the client i get :nfsd: last server has exited
nfsd:
unexporting all filesystems
nfsd: last
server has exited
nfsd:
unexporting all filesystems
portmap:
server localhost not responding, timed out
all time.
There is no problem but sometimes in the client it start to consume a
lot of the processors and I cant to stop it. The service stop ok but it
doesnt "release the usage" of th precessors ... in a top, a see iowait
at 100% or 98% .
What can I do ??
thanx for any help

That is probably 2.6.13 probing for ACL support on the server. It should
be harmless.

Could you explain what you mean by "iowait at 100%"? Normally, iowait is
a process state, (a sleep state actually).
Which process is in this state?
Cheers,
Trond

I have to admit... this gave be a bit of a scare...
but this seem to work for me...
> In the server, I get "svc: unknown version (0)" everytime.
This basically means your server it getting garbage instead
of a valid RPC message...

This does not make much sense they are happening on your
client since they happen when you bring down the NFS server.
> portmap: server localhost not responding, timed out
I would guess this means your network is down...
steved.

That the strange thing... There is not a process at 100% ... and the
first 10 process are at most 1% but the nfs doesnt respond.

Sounds to me as if Steve is right: your network access from that machine
is somehow broken.
Are you able to ping the server from the client when this happens? Can
you also, for instance, log in from that client?
Cheers,
Trond

Ok ... when it happend i will test the comunication between the servers
....
I will add to the kernel :
Provide client support for the NFSv3 ACL protocol extension
Provide server support for the NFSv3 ACL protocol extension
its ok ??

This isn't really necessary unless you want to use ACLs. The server
should be able to return the appropriate error to the client, and the
client will stop probing.

Now, everything is ok:
in the client: load average: 0.06, 0.15, 0.18
and I can see the nfs`s filesystem. But in the server I steel getting:
svc: unknown version (0)
I will change the on-board ethernet card in this server. May be this the
problem??
