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

Question

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 ?

Answer 1

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

Answer 2

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

Answer 3

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.

Answer 4

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()

Answer 5

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

Answer 6

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
