Hi there,

I may have found a clue on this in case anyone's interested:

the FreeBSD box runs on an Intel Atom 230 64-bit CPU

I did more digging and found this:

http://www.freebsd.org/projects/bigdisk/index.html

"An audit is needed to make sure that all reported fields are 64-bit clean. There are reports with certain fields being incorrect or negative with NFS volumes, which could either be an NFS or df problem."

Not sure where to go now, as the last entry in that project is dated 2005 -- again, any tips welcome.

Hi there,

I'm facing an odd problem with an NFSv2 mount. I'm using userland nfsd from a Buffalo TeraStation Pro v1 NAS, running PPC Linux 2.4.20.

r...@leviathan:~# uname -a
Linux LEVIATHAN 2.4.20_mvl31-ppc_terastation #3 Tue Jul 18 09:29:11 JST 2006 ppc GNU/Linux

I am sharing the following filesystem:

r...@leviathan:~# df -k
Filesystem           1K-blocks      Used Available Use% Mounted on
<local filesystems>
/dev/md1             1755708928 979032844 776676084  56% /mnt/array1

/etc/exports looks as follows:
/mnt/array1/data 192.168.2.0/255.255.255.0(rw,sync,insecure)

Mounting this on my Macbook Pro:

Fluffy:~ root# mount_nfs 192.168.2.11:/mnt/array1/data /mnt

Fluffy:~ root# df -k
Filesystem 1024-blocks Used Available Capacity Mounted on
<local filesystems>
192.168.2.11:/mnt/array1/data 1755708928 979032844 776676084 56% /mnt

So far, so good...

Mounting this on a FreeBSD 7.1 client:

behemoth# mount /data
behemoth# df -k
Filesystem 1024-blocks Used Avail Capacity Mounted on
<local filesystems>
192.168.2.11:/mnt/array1/data -391774720 -1168450804 776676084 298% /data

Here is my fstab:

192.168.2.11:/mnt/array1/data   /data   nfs     rw      0       0

Woo.  298%!  That's a record, even for me.

I've tried mount_nfs with -2, -T, and I can't think of anything else. There are no telling log messages, either on the NAS or on the FreeBSD box.

behemoth# uname -a
FreeBSD behemoth 7.1-RELEASE-p2 FreeBSD 7.1-RELEASE-p2 #2: Sat Jan 31 20:13:15 CET 2009 r...@behemoth:/usr/obj/usr/src/sys/ BEHEMOTH i386

Any ideas? It's causing various php scripts that need an accurate filesystem size to puke all over the place. Help!

Thanks much for any thoughts,

-John
