Ahh... this problem is restricted to mainline. We forgot to
pack the vote message while we were pruning it. This problem
is in 2.6.20 onwards.
I'll have the patch fix attached to that bugzilla once I have
tested it.

dear all,
I'm a bit depressed as of now... I upgraded my OCFS2 cluster to the
latest F7 kernel 2.6.22.5-76.fc7 and I can't mount my filesystem on
two PC at the same time, one is 32bit and the other is 64.... any idea

investigating a little bit more, seems like (but not sure) EOVERFLOW
can be thrown only in 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;
}
I guess there could be some 32/64 cleanness problem somewhere...
I'd like to debug it a bit more but I'm not able to activate enough
debugging even after enabling it:
[EMAIL PROTECTED] ~]# /sbin/debugfs.ocfs2 -l /dev/sdc1

.. there must be some 'turn-on debugging log' master switch somewhere...
