[Linux-HA] DC

[Zachár Balázs]

In my case, maybe there is a reason to change the DC:

In my cluster (active/passive 2 node) the B node is the default DC.
If I don't use rsc_location constraints the resources will start on the 
B node (I think, It is because the B is the DC). So I use constraints to 
start they on the A node.

If I use clone pingd. There is a strange thing when I starting the 
heartbeat:
The resources are starting in the A node, but there is a state when the 
B node's pingd value positive (in my case 110) and the A node's value is 
zero and then the cluster failover. After the A node's pingd value 
become positive (110) the resources migrating back.
All of this action were during the start method.

Now I use the ha.cf respawn directive to using pingd.

It is normally?

Thanks,
Balázs
