Re: openais question

Other way to observe the same (maybe other reason??):

After booting both nodes, when doing a service cman start on both nodes 
with some seconds of interval between both commands, the two nodes join 
the cluster and get quored.
When doing service cman stop on both nodes (also with some seconds of 
interval between both commands), one of the nodes successfully leaves 
the cluster, but the other prints this out

[root@m07 ~]# service cman stop
Stopping cluster:
  Stopping fencing... done
  Stopping cman... failed
Timed-out waiting for cluster
                                                          [FAILED]

while the messages in the log are
Dec  7 15:27:17 m07 openais[5436]: [TOTEM] The consensus timeout expired.
Dec  7 15:27:17 m07 openais[5436]: [TOTEM] entering GATHER state from 3.

Do you know what the problem is?

Hi All,

I've a running cluster (v2.01.00) with two Fedora7 nodes. While 
testing I've disabled all the NICs in one node. I started observing 
these messages on the other node:

Dec  7 13:05:55 m07 openais[4233]: [TOTEM] The consensus timeout expired.
Dec  7 13:05:55 m07 openais[4233]: [TOTEM] entering GATHER state from 3.
Dec  7 13:06:10 m07 openais[4233]: [TOTEM] The consensus timeout expired.
Dec  7 13:06:10 m07 openais[4233]: [TOTEM] entering GATHER state from 3.
Dec  7 13:06:25 m07 openais[4233]: [TOTEM] The consensus timeout expired.
Dec  7 13:06:25 m07 openais[4233]: [TOTEM] entering GATHER state from 3.

When I enabled the NICs and network was restored the same messages 
kept appearing, now on both nodes.
I've searched but couldn't find an answer/explanation.

Thanks for your help,
