[Linux-cluster] restart or relocate?

[Carlo Mandelli]

Hi all,

I'm trying to test a 2 nodes cluster (RHCS U4) with apache and one
monitored ip on eth1 (VIP 192.168.0.3), the hearthbeat is on eth0.

When I unplug the cable (eth1) on active node, I get these errors:

<...>

and it restarts the service continously.

It performs failover only if I modify recovery mode in cluster.conf:

<service autostart="1" name="http" recovery="relocate">

Is there any way to set max number of retries before relocate service?

Thanks
