[ovirt-users] Can't ping gluster interfaces for HCI setup

Hi, I'm in the process of trying to set up an HCI 3 node cluster in my homelab to better understand the Gluster setup and have failed at the first hurdle. I've set up the node interfaces on the built in NIC and am using a PCI NIC for the Gluster traffic - at the moment this is 1Gb until I can upgrade - and I've assigned a static IP to both interfaces and also have both entries in my DNS. From any of the three nodes, I can ping the gateway, the other nodes, any external IP but I can't ping any of the Gluster NICs. What have I forgotten to do? Here's the relevant output of 'ip addr show'. em1 is the motherboard NIC and p1p1 is port 1 of an Intel NIC. The /etc/sysconfig/network-scripts/ifcfg-<if> scripts are identical aside from IPADDR, NAME, DEVICE and UUID fields. Thanks, Shareef.
