Re: [Pacemaker] ERROR: Unable to find nic or netmask.
Got it. Changed the netmask for both PCs to 255.255.255.0 and changed cidr_netmask to 24 and it works...sort of. It was working for a while, and then I rebooted both PCs, and now each thinks its online and the other is offline. "pcs status" on my node01 gives the following output: Cluster name: cluster_web Last updated: Tue Sep 2 12:21:25 2014 Last change: Tue Sep 2 12:13:27 2014 via cibadmin on node02 Stack: corosync Current DC: node01 (1) - partition WITHOUT quorum Version: 1.1.10-32.el7_0-368c726 2 Nodes configured 2 Resources configured Online: [ node01 ] OFFLINE: [ node02 ] Full list of resources: virtual_ip(ocf::heartbeat:IPaddr2):Started node01 webserver(ocf::heartbeat:apache):Started node01 PCSD Status: node01: Offline node02: Online Daemon Status: corosync: active/disabled pacemaker: active/disabled pcsd: active/disabled However, "pcs status" on node02 shows the following output: Cluster name: cluster_web Last updated: Tue Sep 2 12:20:41 2014 Last change: Tue Sep 2 11:59:03 2014 via cibadmin on node02 Stack: corosync Current DC: node02 (2) - partition WITHOUT quorum Version: 1.1.10-32.el7_0-368c726 2 Nodes configured 2 Resources configured Online: [ node02 ] OFFLINE: [ node01 ] Full list of resources: virtual_ip(ocf::heartbeat:IPaddr2):Started node02 webserver(ocf::heartbeat:apache):Started node02 PCSD Status: node01: Offline node02: Online Daemon Status: corosync: active/disabled pacemaker: active/disabled pcsd: active/disabled Seems like each node thinks it's online and the other is not. I'm running HA on apache webserver, and if I access the webpage on node01, I get node01's index.html. If I access it on node02, I get node02's index.html. If I access it via another PC connected to the same AP, the webpage is unavailable. What could be wrong?

[Pacemaker] ERROR: Unable to find nic or netmask.
Hi, I'm trying to create a HA cluster with 2 CentOS 7 PCs connected to a wireless AP. The PCs have the static IP addresses 192.168.0.111 and 192.168.0.112 respectively and hostnames node01 and node02 respectively. I've tried to create a virtual IP address of 192.168.0.110 using the following command: pcs resource create virtual_ip ocf:heartbeat:IPaddr2 ip=192.168.0.110 cidr_netmask=32 op monitor interval=30s However, when I do a "pcs status resources" I get the following output: virtual_ip(ocf::heartbeat:IPaddr2):Stopped The virtual IP is stopped rather than started. I looked into /var/log/messages and /var/log/pacemaker.log and I find the following error messages: node02 IPaddr2(virtual_ip)[25451]: ERROR: Unable to find nic or netmask. node02 IPaddr2(virtual_ip)[25451]: ERROR: [findif] failed It seems that it's unable to find my nic. How can I fix this?
