Re: [Linux-cluster] all nodes halt when one lose connection



Hi, 

I think this is not my problem because fencing works fine. The nodes gets fenced inmediatly but I think they fence when they don't must

Hello,

these are the logs I get:

In node1:

May 21 11:33:44 NODE1 fenced[3840]: NODE2 not a cluster member after 5 sec post_fail_delay
May 21 11:33:44 NODE1 fenced[3840]: fencing node "NODE2"
May 21 11:33:44 NODE1 shutdown[5448]: shutting down for system halt

in node2:

May 21 11:33:45 NODE2 fenced[3843]: NODE1 not a cluster member after 5 sec post_fail_delay
May 21 11:33:45 NODE2 fenced[3843]: fencing node "NODE1"
May 21 11:33:45 NODE2 shutdown[5923]: shutting down for system halt


what I don´t know is way they lose the connection with the cluster, they are still connected (I only unplug a cable from the service network)

That may be something worth chasing down, as it appears that your cluster communication is on a network you don't expect?

How can I be sure about the network the nodes are using for communication? I think they do for the network I have configured to do that....
 

Also, are the nodes simply "shutting down", or are they being forcibly rebooted.  If it is a casual shutdown, then it would appear that both nodes are trying to shutdown simultaneously.

they simply shutdown. They no reboot.

This is what I get every time I unplug the nework cable from eth0 of any of the two nodes. (they communicate through eth1...)
