[ClusterLabs] Pacemaker and Oracle ASM

Hello: I'm working on a project where the client is using Oracle ASM (volume manager) for database storage. I have implemented a cluster before using LVM with ext4 and understand there are resource agents (RA) already existing within the ocf:heartbeat group that can manage which nodes connect and

Re: [ClusterLabs] Corosync ring shown faulty between healthy nodes & networks (rrp_mode: passive)

Thanks for all responses from Jan, Ulrich and Digimer ! We are already using bond'ed network interfaces, but we are also forced to go across IP-subnets. Certain routes between routers can go and have gone missing. This has happened for one of our node's public network, where it was inaccessible

Martin Schlegel napsal(a): Thanks for the confirmation Jan, but this sounds a bit scary to me ! Spinning this experiment a bit further ... Would this not also mean that with a passive rrp with 2 rings it only takes 2 different nodes that are not able to communicate on different networks at the
