[Ocfs2-users] o2net_check_handshake ... advertised net protocol version 11 but 8 is required

Hi,
we have two node HP Proliant DL140 / Ubuntu 8.04 LTS / Heartbeat 2.1.3-2 
cluster with bunch of KVM virtual guests. Images for virtual servers are 
stored in two DRBD 8.0.11 / OCFS2 1.3.9 dual-primary mode resources.
I've run this cluster for one year yet and I need to upgrade it now. I
can't
stop cluster and upgrade both nodes at once. So I moved all virtual servers 
to one node, stopped Heartbeat, OCFS2 and DRBD and upgrade another node to 
Ubuntu 8.10. All seems to be well after reboot except I'm not able mount 
OCFS2/DRBD partitions on upgraded node:

~# mount -t ocfs2 /dev/drbd1 /drbd1/
mount.ocfs2: Transport endpoint is not connected while mounting /dev/drbd1 
on /drbd1/. Check 'dmesg' for more information on this error.

Tail of dmesg on upgraded node:

And on non-upgraded node:

1) at 10.123.45.19:7777 advertised net protocol version 11 but 8 is required, 
disconnecting

Configuration files are the same on both nodes:

#/etc/ocfs2/cluster.conf
node:
        ip_port = 7777
        ip_address = 10.123.45.18
        number = 0
        name = rrhb-gandalfb
        cluster = ocfs2
node:
        ip_port = 7777
        ip_address = 10.123.45.19
        number = 1
        name = rrhb-gandalfs
        cluster = ocfs2
cluster:
        node_count = 2
        name = ocfs2

Along to this thread 
http://oss.oracle.com/pipermail/ocfs2-users/2008-April/002769.html it could 
be kernel incompatibility problem. Is it chance to solve it anyhow with 
different kernels? I need to keep one node running continually so I'm afraid
to upgrade it while the other one won't be OK. Thanks for your advice.

Tomas

[Ocfs2-users] o2net_check_handshake ... advertised net protocol version 11 but 8 is required

Hi Mr. Tomas,

You need the same version of OCFS2 drivers in both nodes to mount the
volume. The OCFS2 versions are on-disk compatible but the
network protocol can change. It seems your problem.

Regards,
S?rgio
