This feature request did not get resolved in time for Feature Freeze for the current Red Hat Enterprise Linux release and has now been denied. You may re-open your request by requesting your support representative to propose it for the next release. sdake, can you provide some information on how udpu would be configured in Corosync and used? This will give us a better idea of what other areas (aside from Luci) need integration work. Example config files would help here I think. For example, will we need to expose udpu configuration as part of cluster.conf? That will mean cloning this bug for cluster component as well and making sure we update the schema. Bug #657041 is the cman bugzilla related to this RFE. The patch has been merged into stable31 to support this feature. From corosync.conf man page:
member This specifies a member on the interface and used with the udpu
transport only. Every node that should be a member of the mem-
bership should be specified as a separate member directive.
Within the member directive there is a parameter memberaddr
which specifies the ip address of one of the nodes.
An example corosync.conf showing 16 nodes is attached to this bugzilla.
In the case of cman, the "transport" should be changed to "udpu". Honza will provide necessary information to make that work in Bug #657041.
