>>@alexandre: what switch model do you use? production: cisco 6500 WS-X6548 modules
test : cisco 2960g Both have igmp snooping manually disabled. Note that my main problem was that, when shutting down a node of the cluster, after 2 min, all nodes linux bridges blocked the multicast traffic. Now, I see that old kernels (include redhat), send igmp queries by default when igmp snooping module is enabled This behaviour have change last year, http://patchwork.ozlabs.org/patch/152295/ Because it can conflict with igmp of physical switchs ----- Mail original ----- De: "Dietmar Maurer" <diet...@proxmox.com> À: "Michael Rasmussen" <m...@datanom.net>, pve-devel@pve.proxmox.com Envoyé: Vendredi 8 Mars 2013 18:51:33 Objet: Re: [pve-devel] corosync, multicast problem because of vmbr multicast_snooping enabled > > But Indeed, that's not an easy update,i'm not sure it's possible to push it > > by > default to next kernel. > > > You are certain that it is not your switch which is causing problems? @alexandre: what switch model do you use? _______________________________________________ pve-devel mailing list pve-devel@pve.proxmox.com http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-devel _______________________________________________ pve-devel mailing list pve-devel@pve.proxmox.com http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-devel
