This is most definitively a build issue. But "what" is unknown.
How comfortable are you playing with the source? If so,
I could guide you in debugging the issue. If not, I can make
a patch that you could build and run.
In short, the error is originating from here.
fs/ocfs2/cluster/tcp.c
if (sc->sc_page_off == sizeof(struct o2net_msg)) {
hdr = page_address(sc->sc_page);
if (be16_to_cpu(hdr->data_len) >
O2NET_MAX_PAYLOAD_BYTES)
ret = -EOVERFLOW;
}

Hallo,
I have two servers and both are connected to external array, each by
own SAS connection. I need these servers to work simultaneously with
data on array and I think that ocfs2 is suitable for this purpose.
One server is P4 Xeon (Gentoo linux, i386, 2.6.22-r2) and second is
Opteron (Gentoo linux, x86_64, 2.6.22-r2). Servers are connected by
ethernet, adapters are both Intel EtherExpress1000.
Firstly, I compiled ocfs2 modules, which is provided with kernel and
then I downloaded and compiled ocfs2-tools (1.2.6). In accordance with
manual I made file cluster.conf, loaded modules and mounted /config
and /dlm. On both systems external array is /dev/sdb, so I made linux
partition /dev/sdb1 and ocfs2 filesystem on it. Cluster is started by
command
# /sbin/o2cb_ctl -H -n clust -t cluster -a online=yes
on both servers.
If I mount filesystem on one server, all is OK. I can read and write
files on filesystem and second server can see first's server
heartbeating.

Problem appears, when I try to mount filesystem on both servers. First
case is, when serv_i386 has filesystem mounted and serv_x86_64
attempts to mount filesystem too. After about 14 seconds appears this
message:
---------------
serv_x86_64 # mount -t ocfs2 /dev/sdb1 /ext_arrays/ds3200_1/
mount.ocfs2: Value too large for defined data type while mounting
/dev/sdb1 on /ext_arrays/ds3200_1/. Check 'dmesg' for more information
on this error.

In serv_x86_64's dmesg are following lines
----------------

When I'm trying to connect servers conversely (first x86_64), then
mount stales and it is impossible to break it or unmount mounted
filesystem on other machine.Firewall is down, listings are at end of
this email.
Can anybody help me with this problem, please?
Thanks,
