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? Thanks.
