You might want to try "ip a" vs ifconfig. RHEL7 uses Network
Manager and in the past I've found some things don't show up in
ifconfig output when doing alias/virtual interfaces.
Usually even when other products (e.g. Oracle RAC/GRID) create
virtual interfaces they still show up as valid interfaces at host
level. I've not tried PCS/Corosync.
That's not how pcs/corosync does it IIRC. They're active on one node
only, usually as secondary IPs on the physical ethernets; dual active
doesn't work properly in that situation anyway due to ARP fighting and
other issues.
OP will need to use a different approach to make bind work in this kind
of setup.
