Good morning. After updating from 5.4-3 to 5.4-5 on my 7 node cluster I experience a complete network failure of all VMs in the cluster if I shutdown any one node. Once the node goes down we also lose the ability to console into any VM and the VMs all disconnect from the network. If we restart the node, once it returns online, normal operation occurs and the VMs are all reachable and in the same state they were in. This was not the experience prior to 5.4-5 so I'm curious if we've experienced a bug of sorts. What information can I supply to help us with this issue? I have need to shutdown 5 of the nodes for hardware maintenance (two were done last week before the patch without issue). Thanks!
