NetBSD barney.hinyx.info 3.0 NetBSD 3.0 (GENERIC) #0: Mon Dec 19 01:04:02 UTC 2005 builds@works.netbsd.org:/home/builds/ab/netbsd-3-0-RELEASE/i386/200512182024Z-obj/home/builds/ab/netbsd-3-0-RELEASE/src/sys/arch/i386/compile/GENERIC i386
>Description:
I export an ext2fs partition using NFS.
When I mount it on a Solaris box, it works using either NFSv2 and NFSv3.
However, when mounting it on a Linux box, NFSv3 doesn't work.
root@babe:~# mount -t nfs -o nfsvers=3 barney:/big /big
root@babe:~# ls /big
ls: reading directory /big: Input/output error
root@babe:~# umount /big
root@babe:~# mount -t nfs -o nfsvers=2 barney:/big /big
root@babe:~# ls /big
[Directory listing comes here]
Same problem when using an SCO OpenServer client, but here with both NFSv2 and NFSv3:
bart#truss ls /big 2>&1 | grep EIO
getdents(3, 0x08329B70, 2048) Err#5 EIO
(have to use truss because `ls' doesn't print out any error message)
Here's the tcpdump output when running `ls' on /big with NFSv3 under Linux:
08:35:47.552875 IP (tos 0x0, ttl 64, id 54812, offset 0, flags [DF], proto: TCP (6), length: 52) babe.hinyx.info.1023 > barney.hinyx.info.nfs: ., cksum 0x53a5 (correct), 2156:2156(0) ack 1685 win 1728 <nop,nop,timestamp 16794340 72>
08:35:57.296691 IP (tos 0x0, ttl 64, id 54813, offset 0, flags [DF], proto: TCP (6), length: 196) babe.hinyx.info.4274594373 > barney.hinyx.info.nfs: 144 getattr [|nfs]

[stops here]
Here's the uname -a output of the Linux box:
# uname -a
Linux babe 2.6.15-26-sparc64 #1 Thu Aug 3 02:59:18 UTC 2006 sparc64 GNU/Linux
It's an Ubuntu Server 6.06.1.
And by the way, if I suspect ext2fs, it's because the NetBSD machine exports an ffs NFS share as well, which works perfectly using NFSv3 on Linux and SCO boxes.
>How-To-Repeat:
Simply export an ext2fs partition using NFS and mount it with NFSv3 on a Linux box.
>Fix:
Using NFSv2 could be a workaround for Linuxes box.
Didn't found a fix for SCO OpenServer.

Can you also run uname -a on the linux box too? It looks to me that
you are running an older kernel that does not support nfsv3 properly.
Can you export a nfsv3 partition from solaris and mount it on linux
and see if that works? It looks like a problem on the linux side.

As you see, I don't think it's due to an old version of Linux.
Notice that the problem also occurs on SCO OpenServer.
However, it works okay with an OpenBSD box:
neptune>uname -msr ; /sbin/mount | grep big
OpenBSD 3.9 sparc
barney.hinyx.info:/big on /big type nfs (v3, udp, timeo=100)
So the problem only occurs against a Linux 2.6.15 (and probably with
earlier version--it has been a long time since I had to force NFSv2 with
every Linux boxes) and SCO OpenServer.
Thanks,
Thomas
