Almost all our tools can actually. http://www.clusterlabs.org/doc/en-US/Pacemaker/1.0/html/Pacemaker_Explained/ch-advanced-options.html#s-remote-connection > >> >> On 10/26/10, Serge Dubrouski <[email protected]> wrote: >>> On Tue, Oct 26, 2010 at 12:24 PM, David Quenzler <[email protected]> wrote: >>>> How about something like... >>>> >>>> Cluster with 4 nodes: node1 node2 node3 node4 >>>> >>>> ResourceA runs only on node1 and node2, never on node3 or node4 >>>> ResourceB runs only on node3 and node4, never on node1 or node2 >>> >>> Just curios, what is the point of building a 4-node cluster in this >>> case instead of 2 clusters of 2 nodes each? >>> >>>> >>>> On 10/26/10, Pavlos Parissis <[email protected]> wrote: >>>>> On 25 October 2010 19:50, David Quenzler <[email protected]> wrote: >>>>> >>>>>> Is there a way to limit failover behavior to a subset of cluster nodes >>>>>> or pin a resource to a node? >>>>>> >>>>>> >>>>> Yes, there is a way. >>>>> >>>>> Make sure you have a asymmetric cluster by setting symmetric-cluster to >>>>> false >>>>> and then configure accordingly your location constraints in order to have >>>>> the failover domains as you wish. >>>>> >>>>> Here is en example from my cluster where I have 3 nodes and 2 resource >>>>> group.
