Hi

I've noticed that my qemu guest is now unable to use localy exported
nfs directory.
Directory gets mounted, plain 'ls' shows filenames - but nothing else
could be done.

ls -la gives this output:
ls: cannot access patch: Input/output error
...


Both host & guest are running same kernel:
851b147e4411df6a1e7e90e2a609773c277eefd2

I've checked last few commits and tried to revert them -
and this one seems to cure my problem when reverted:

Sep 23:  8a6e5deb8a8caa810fef2c525f5dbea2cfe04a47
NFS: Get rid of the NFS_MOUNT_VER3 and NFS_MOUNT_TCP flags

I should also probably note that I'm seeing this message in my dmesg log:
svc: failed to register lockdv1 RPC service (errno 97)

What does

   cat /proc/self/mountinfo

give you?

Working version: (kernel 2.6.31 or current git with reverted NFS patch)

22 12 0:17 / /misc rw,relatime - autofs automount(pid1720)
rw,fd=4,pgrp=1720,timeout=300,minproto=2,maxproto=4,indirect

24 22 0:19 / /misc/kabi rw,relatime - nfs IP:/home/kabi/export
rw,vers=3,rsize=524288,wsize=524288,namlen=255,soft,proto=tcp,port=65535,timeo=600,retrans=2,sec=sys,mountaddr=IP,mountvers=3,mountproto=tcp,addr=IP


Nonworking version:

22 12 0:17 / /misc rw,relatime - autofs automount(pid1704)
rw,fd=4,pgrp=1704,timeout=300,minproto=2,maxproto=4,indirect

24 22 0:19 / /misc/kabi rw,relatime - nfs IP:/home/kabi/export
rw,vers=2,rsize=8192,wsize=8192,namlen=255,soft,proto=tcp,port=65535,timeo=600,retrans=2,sec=sys,mountaddr=IP,mountvers=3,mountproto=tcp,addr=IP



Looks like vers=2  != vers=3   and rsize/wsize - which is also set by
the kernel itself to those lower values.
(i.e. my /etc/init.d/autofs doesn't modify localoptions - of course I
could use this to set 8192 wsize and rsize for my working kernel)

Thanks for the report! I'll take a look at this over the weekend...

OK. The following patch fixes the default nfs version issue for me. I
have another one to fix the incorrectly displayed port numbers...

Cheers
  Trond
------------------------------------------------------------------------
NFS: Fix a default mount regression...
From: Trond Myklebust <Trond.Myklebust@netapp.com>

With the recent spate of changes, the nfs protocol version will now default
to 2 instead of 3, while the mount protocol version defaults to 3.

The following patch should ensure the defaults are consistent with the
previous defaults of vers=3,proto=tcp,mountvers=3,mountproto=tcp.
