Hi,

I deployed an openstack cloud with Mirantis Fuel, it works fine. but when I move some hardware to deploy a new openstack cluster, the cobbler docker container allocate ip address to new hardwares, but doesn't allocate host names.

I can find the new hardware in Mirantis Fuel UI, add nodes page. the status of these hardware are "DISCOVERED".

normally when a new hardware is put into the environment, it will be added to the file /etc/dnsmasq.conf, with a line like below:

dhcp-host=net:x86_64,74:c9:9a:4f:ba:c8,node-60.domain,192.168.250.48

and under folder /var/log/remote, there should be a link from ip address to the hostname

lrwxrwxrwx 1 root root   29 May  5 10:38 192.168.250.48 -> node-60.domain

but now when the hardware "discovered" in Mirantis, I can not see any dhcp-host added to dnsmasq.conf file, and a folder with the allocated ip address will be created under /var/log/remote, instead of node-xx.domain.

drwxr-xr-x 3 root root   22 May  6 15:12 192.168.250.49

Is there any way to clean up these hardware discovery history in Fuel and force it to re-discover hardware and allocate host name again?

Thanks to omar-munoz! it's found that cobbler didn't update the discovered node.
