[Ocfs2-users] CRS keeps killing the other node.

[Irwan Hadi]

I have an Oracle RAC test environment that consists of 2 nodes. The
nodes are running Redhat ES4 update 2.
These two nodes are using a firewire disk with OCFS2 filesystem as shared disk.

Oracle Clusterware is installed perfectly fine on these two nodes.

The problem now is, it seems the hosts always kill (fence) each other.
For example, say currently node 1 is hang (fenced), and node 2 is
active. If I cold restart node 1, node 2 in a few minutes will hang
(fenced) with caps lock and scroll lock blink continuously.
Now if I cold restart node 2m then node 1 will hang (fenced) with caps
lock and scroll lock blink continuously.

This is the output of syslog from one of the nodes:

This is the one from testdb01:

Does anybody know what is going on?
