Subject: NFS on 2.6.0-test9

On a kernel 2.6.0-test9 as an NFS client I am having trouble transferring
data to and from NFS servers. It it extraordinarily slow.??I?receive?the
following information in dmesg:

nfs warning: mount version older than kernel
nfs: server safe not responding, still trying
nfs: server safe not responding, still trying
nfs: server safe not responding, still trying
nfs: server safe not responding, still trying

I have also upgraded util-linux to 2.12pre

I am using various NFS servers, Solaris 2.8, Solaris 2.6, linux 2.4 and of
all things a windows server with NFS. It seems to suffer when connecting to
any one of them.

I have built from the default 2.6.0-test9 source.

I see that one, too. Apart from that, it appears to work. Try the
tcp option, and see if it helps.

tcp option seems to have helped, except when attempting to mount a
redhat 9 nfs server. Mount says:
"nfs server reported service unavailable: Address already in use"

Maybe the NFS server in RH9 doesn't support TCP mounts. I just spent
the better part of the afternoon fighting with almost every other
aspect of an RH9 system, so nothing surprises me when it comes to
redhat. They even ship a broken perl.
