Lost DNS entries for machines managed by MAAS

[Jonas Wagner]

Hello,

Any further advice on this issue? I've tried a few more things, but all
without success:

- Link the nodes' interfaces to a subnet. This doesn't work: Cannot link
subnet interface because the machine is not Ready or Broken.

- Update the dnsresource corresponding to the node's hostname. Trying the
command "maas foo dnsresource update 2 ip_address=10.0.10.114". This
returns "Success" but seems to have no effect.

- Create an ipaddress. Trying the command "maas foo ipaddresses reserve
ip=10.0.10.114 hostname=bar.maas mac=52:54:00:89:04:fb". This tells me "IP
address 10.0.10.114 belongs to an existing dynamic range. To reserve this
IP address, a MAC address is required. (Create a device instead.)"

Any more hints are appreciated. Cheers,
Jonas
