Description Steven Dake 2009-05-12 08:35:44 UTC

+++ This bug was initially created as a clone of Bug #492808 +++

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."

--- Additional comment from sdake on 2009-03-31 16:29:59 EDT ---

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?

--- Additional comment from sdake on 2009-03-31 17:02:43 EDT ---

in response to #2 if the field wants this feature supported in conga, they can file a separate configuration rfe bugzilla for conga.

This patch requires work for corosync.  Also Honzaf please work with Chrissie to work up a patch for cman to allow setting of this feature.  It may involve some configuration options - Fabio is the person to talk to there.

Honzaf,

can you take this bug back over for corosync trunk.  You can probably forward port the whitetank patch mostly unchanged.

Regards

Chrissie made that patch, so I'm reassign bug.

Comment 4 Christine Caulfield 2009-06-01 15:13:15 UTC

The code is now in the latest openais, corosync and cman.

Comment 5 Steven Dake 2009-09-28 14:40:31 UTC

added in f11, f10.
