  • Overview - mysql-master-ha - MHA for MySQL: Master High Availability Manager and tools for MySQL - Google Project Hosting

    MHA performs automating master failover and slave promotion with minimal downtime, usually within 10-30 seconds. MHA prevents replication consistency problems and saves on expenses of having to acquire additional servers. All this with zero performance degradation, no complexity (easy-to-install) and requiring no change to existing deployments.

    Problème des caches ARP ? Les clients ont l'adresse MAC du serveur qui est tombé, quand le serveur ne répond pas en face, est-ce que le client va refaire une arp request ? sinon peut-on forcer les clients à le faire ? sinon peut-on utiliser un ARP gratuitous ? Comment de manière sécurisée ?

    EDIT : une solution avec les ARP gratuitous : https://devcentral.f5.com/articles/the-limits-of-cloud-gratuitous-arp-and-failover#.UnoP_kO4DRY
