[Keepalived-devel] keepalived partition handling and quorum

[Howley, T. <tom...@hp...>]

Hi,

I'm relatively new to keepalived, so apologies in advance. I have a relatively simple keepalived setup with a single vrrp instance that is managing a single VIP across three nodes. The only point worth noting is that my config is identical across all three nodes, so the ip address is used in the original Master election. I'm wondering if VRRP has a concept of quorum handling. I basically want to avoid the scenario where a network partition (which could be isolated to just a multicast failure) results in two nodes of the cluster claiming to hold the VIP. For example if a node that was Master becomes isolated, can I configure it to disassociate the VIP from itself?

I have just tried adding some LVS config, specifying a pool of real servers, so that I now have a script that is invoked if either quorum is lost or regained. So I could possibly use that to do what I want, but it feels like I'm going the road of hackery.

Any advice on this?

Thanks,
Tom
