Many customers are interested in using RHCS but face a stumbling block with their network equipment and/or network standards with regard to multicast. Submitting this RFE to provide an alternate means for cman's "heartbeats."
5.4 flags set to add "broadcast" option instead of multicast option. Requires small change to cman as well as openais.
(In reply to comment #1) > 5.4 flags set to add "broadcast" option instead of multicast option. Requires > small change to cman as well as openais. Impact to openais/cman are fairly minor, but what about impact to higher level tools like Conga? Will there be ripple effect to other components?
chrissie are you ok with this change in cman config parameters?
in response to #2 if the field wants this feature supported in conga, they can file a separate configuration rfe bugzilla for conga. regards -steve
Honzaf, Once corosync feature is finished, backport to whitetank and stable 2. Thanks! -steve
Yes, I'm very happy to make the changes to cman to support broadcast. I'm fairly sure it will be a small change.
