Hi. I was running fuel in a VM named *fuel*. So actually what happened was that, while removing some of my routes from the iptables, I mistakenly deleted the ipaddress on eth0 (PXE network). So I lost connection with the fuel node. However, quite interestingly, on my base machine running the fuel, I was able to observe that another instance with name *fuel-master *had sprung up.
It had the same IP address on eth0 as the previous one, but it did not have routes to the compute and controller nodes, hence the errors I previously asked about. For now, I have shutdown this instance, i.e *fuel-master, *and rebooted the original one (fuel). Its working fine for now. It is able to detect the pool of unallocated machines and have also successfully deployed a new cluster. Is there any explanation for the above, and would it cause complexities in the future ? Thank you.
