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?

Assuming a proper netmask (not > 255.255.255.2555) is on 192.168.0.111 and 192.168.0.112 it should work > without specifying cidr_netmask. > > > ------------------------------ > > *From: *"Sihan Goi" <gois...@gmail.com> > *To: *pacemaker@oss.clusterlabs.org > *Sent: *Monday, September 1, 2014 4:17:20 AM > *Subject: *[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.
