[Linux-HA] Looking for efficient STONITH device - must not be single-point-of-failure

Hi all, well to be honest I don't know that much about STONITH yet, but I know what it's supposed to do. In our setup we have only 2 nodes, running Heartbeat 2.14 connected via a cross-over cable (side question, is it possible to use more then one NIC to connect the two servers, thus when one fai

[Linux-HA] STONITH / ssh not working in a 2-node cluster

Hi, I know I should use it only for development purposes and that's what I am doing right now. I have configured my cluster and a resource stonith_ssh. I configured stonith_ssh to use the external IP address to connect to the other server. When I ran: 'stonith -t ssh -p "nagios1.hq.xxx" -T reset

Just guessing, but your cluster does not know about those "external" addresses, does it? Sounds like you're only using one connection between the nodes for cluster communication, pull that, see split-brain and want the cluster to use a connection it does not know about. But even if you configured

RE: [Linux-HA] Write requires Quorum, Setting up LVM resource fails

Thanks Andrew, It is fixed. it is working now with four node, four resources group. four virtual IPS, six LVM resource and six filesystem resource spread across all four node. Next step will be setting up nfs fail over that will be fun. I can't find any NFS ocf script. Defaulting to one-sho

RE: [Linux-HA] Failover not working as I expected

I would just like to thank everyone who has helped me get HA (Pacemaker) working. It works really really nice. You guys were right. It was a bug in the RA. As soon as I fixed it, Pacemaker worked like a charm. Regards, jerome -Original Message- From: linux-ha-boun...@lists.linux-ha.

RE: [Linux-HA] RE: Help with STONITH Plugin

Can the resource definition be captured or exported? Would that be part of the plugin script itself? I can send any useful debug information that can be captured from the system if you can provide some guidance on what would be helpful. Thanks, Joe -Original Message- From: linux-ha-b
