Trouble with Setting Up LXD Clusters in MAAS
Hello! I have been working with maas to try and setup a LXD cluster.
Setup
- Maas Controller: Dell Optiplex (nothing special, just an extra computer that I had around.) The MAAS controller is setup as the DHCP server for the network. I just have one fabric with a 10.113.1.0/24 subnet for no particular reason. Setup is mainly proof-of-concept for now.
- MAAS clients: 3x Dell PowerEdge T630's with Intel 10GB network cards and IPMI.
Versions
- Maas Controller:
$ snap list | grep maas
maas 3.2.0~beta6-11974-g.58f181df4 21449 3.2/beta canonical** -
maas-cli 0.6.5 13 latest/stable canonical** -
maas-test-db 12.4-22-g.aed1dfe 91 3.1/stable canonical** -
(This was also tested with 3.1/stable with the same results.)
- The Dell PowerEdge servers are deployed with MAAS with the Ubuntu 22.04 LTS cloud image.
$ cat /etc/os-release

What I have tried
I have tried following the following articles:
I am able to get the LXD cluster going using lxd init on the first Dell PowerEdge server and following the prompts. I then add the other two PowerEdge's using lxd init again and copy/pasting their join tokens. However, when I add the LXD host from the maas KVM page, it just shows up as a single cluster.

Images:
- Adding LXD Host from KVM Dashboard.
- Copying LXD trust.
- Pasting LXD trust to LXD leader.
- Confirming that the trust was added successfully.
- MAAS only shows that the LXD cluster is a single host.
Thanks in advance to anyone who helps!
