Thanks for the information.

Any advice on the best way to know whether the node I'm running on is the "active" node ?

There are no resources that are local to a given node.
Hence, I suppose that I should never get the "foreign" or "local" status.
Am I correct ? ;-)

As far as I understand this, "local" and "foreign" could only happen if, say, I have a different
haresources definition on node 1 than on node 2, with e.g. some haresources that are only defined on
node 1.

My current /etc/ha.d/haresources is as follows:
lvs1    10.10.2.10/24 mon rinetd apache2

where "lvs1" = the preferred cluster node, "10.10.2.10/24" = the cluster VIP

I have exactly the same haresources definition on the 2nd node.

Could I still end up with a resource status "foreign" or "local" in the cl_status output ?

cheers
