How do I delete a node from MAAS after removing it from Cobbler?

I've installed ubuntu maas server, and a couple of nodes. Everything went right, just for one node, now with status "Allocated to...". Question is, how do i delete this node. I've tried following :

cobbler system remove --name=xxx 

The node seems to be removed (cobbler system list) but is still visible in /MAAS webui, even after several reboots.

Any hint ?

maas has its own database, api, and management tools, directly removing things from cobbler is not supported.

sudo maas shell > from maasserver.models import Node > node = Node.objects.get(hostname='myhostname') > node.delete() 

If this problem appeared after juju bootstrap, you can use

juju destroy-environment 

maas flush will rebuild maas enviroment, that's not a good idea.

I faced this problem recently and I'll post here even if this is a very old question. In may case, the node was already allocated to MAAS, so I first had to de-allocate it (with release()) and then delete it. I used the following commands:

sudo maas shell >>> from maasserver.models import Node >>> node = Node.objects.get(hostname='node-name') >>> node.release() >>> node.delete() 

Try to use after that cobbler command... maas flush. It will reset your maasdb.

I faced the same problem. I deployed a testing system and just use

sudo maas flush

but this will remove all tables from your system and start from scratch. will be also useful the

cobbler system remove --name

with the old nodes
