Yeah, I learned about it from Fabio, thought it would be a cool idea, and eventually we sponsored Harald to make it happen. It's shipping in SLES9, and we're adding full support for it in the 2.0 heartbeat cluster resource manager.=20 It's meant to complement the LVS / mod_backhand based approaches. If the proc file IO for communicating with the module goes away in favour of a commandline based add/list/remove/etc interface, that would just help to tidy up our code, so it's OK with me. > > And yes, I've received hate mail over this from switch engineers :-) > Why is that?

Yeah, but with this they get a whole lot more ;-) Sincerely, Lars Marowsky-Br=E9e --=20 High Availability & Clustering SUSE Labs, Research and Development SUSE LINUX AG - A Novell company
