That said it would of course be interesting - once knet-layer or whatever is setup - to be able to use redundancy for pcs. Excuse my ignorance if there is something available already. One thing that might be relatively easy to setup might be a virtual ethernet-connection via knet. Haven't played with that myself so others might be a better help to configure that - if pcs doesn't already have support for such a setup.

If you're referring to the "Offline" under "PCSD Status", yes, that's normal. That only affects the pcsd daemon used to coordinate pcs commands across all nodes, not the cluster itself. As far as I know, pcsd has no way to use multiple links. The "online" under "Nodes" is what's relevant to the operation of the cluster itself. -- Ken Gaillot ___ Manage your subscription: https://lists.clusterlabs.org/mailman/listinfo/users ClusterLabs home: https://www.clusterlabs.org/
[ClusterLabs] cluster with redundant links - PCSD offline
Hi guys. I have a simple 2-node cluster with redundant links and I wonder why status reports like this: ... Node List: * Node swir (1): online, feature set 3.16.2 * Node whale (2): online, feature set 3.16.2 ... PCSD Status: swir: Online whale: Offline ... Cluster's config: ... Nodes: swir: Link 0 address: 10.1.1.100 Link 1 address: 10.3.1.100 nodeid: 1 whale: Link 0 address: 10.1.1.101 Link 1 address: 10.3.1.101 nodeid: 2 ... Is that all normal for a cluster when 'Link 0' is down? I thought redundant link(s) would be for that exact reason - so cluster would remain fully operational. many thanks, L.___ Manage your subscription: https://lists.clusterlabs.org/mailman/listinfo/users ClusterLabs home: https://www.clusterlabs.org/
