I think there is a problem, from "cman_tool status" shows:
Nodes: 2
Expected votes: 3
Total votes: 2
according to your cluster.conf , if all nodes and qdisk are online, the
"Total votes" must be "3". Probably "qdiskd" is not running, you can
use " cman_tool nodes" to check if qdisk is working.

Hi Mockey,
Could you please attach the output from " cman_tool status " and "
cman_tool nodes -f" ?
Thanks your response.
I try to run cman_tool status on as-2, but it hang, without output, and
even Ctrl+C also no effect.
I manually reboot as-1, and the problem solved.
There is the output of cman_tool

It seems cluster can not fence one of the node. How to solve it ?
I open a new window and can using ssh to as-2, but after login, I can
not do anything, even a
simple 'ls' command is hung.
It seem the system keep alive but do not provide any service. Really bad.
Any way to debug this issue ?

To test one node lost heartbeat case, I disable ethereal card (eth0) on
as-1, I expect as-2 takeover services on as-1 and as-1 node reboot.
The actual is as-1 lost connection to as-2. as-2 detected it and try to
re-construct cluster, but failed, here is the syslog form as-2
