Good morning,

We had a storage crash early this morning that messed up a couple of our ovirt hosts. Networking seemed to be the biggest issue. I have decided to remove the bridge information in /etc/sysconfig/network-scripts and ip the nics in order to re-import them into my ovirt installation (I have already removed the hosts).

One of the NIC's refuses to come up and is generating the following error:

ERROR     : [/etc/sysconfig/network-scripts/ifup-eth] Error, some other host (0C:C4:7A:5B:11:5C) already uses address ###.###.###.###.

When I ARP on this server, I do not see that Mac address - and none of my other hosts are using it either. I'm not sure where to go next other than completely reinstalling Centos on this server and starting over.

Ovirt version is oVirt Engine Version: 3.5.0.1-1.el6

OS version is 

CentOS Linux release 7.4.1708 (Core) 

Thank you
