MAAS 节点拒绝 DHCP 分配给它的 IP 地址

我正在尝试在测试环境中配置 MAAS 和 Juju。我的 MAAS 区域和集群控制器位于一台具有两个 NIC 的机器上。eth1 连接到具有互联网访问权限的 LAN；IP 为 192.168.181.32。eth0 是私有网络。我已将其配置为使用 192.168.212.0/24。

MAAS 配置为管理 eth0 上的 DHCP 和 DNS。我已向集群添加了 3 个节点，所有节点都报告状态为“就绪”。但是，当我尝试引导 Juju 时，一切都变糟了：

> juju bootstrap --upload-tools
WARNING ignoring environments.yaml: using bootstrap config in file "/home/dannyb/.juju/environments/maas.jenv"

Waiting for address
Attempting to connect to cloud2.maas.allworx.com:22
Attempting to connect to 192.168.212.8:22

到目前为止一切顺利。云2节点启动并连接到 PXE，但随后我开始得到：

IP-Config: eth0 hardware address 08:00:27:1d:ea:91 mtu 1500 DHCP RARP
hostname cloud2 hostname cloud2 hostname cloud2 hostname cloud2 IP-Config: no response after 2 secs - giving up
IP-Config: eth0 hardware address 08:00:27:1d:ea:91 mtu 1500 DHCP RARP
hostname cloud2 hostname cloud2 hostname cloud2 hostname cloud2 IP-Config: no response after 3 secs - giving up

etc...

我的集群控制器上的系统日志显示：

看起来节点获得了 192.168.212.8 地址，并使用它来下载内核和 initrd，但是一旦内核启动并初始化节点上的 eth0 接口，它就会拒绝接受 212.8 地址，并坚持使用 212.6 地址，而 DHCP 服务器并不想给它这个地址。

有任何想法吗？

我遇到过类似问题，但并不完全相同。我将其追溯到为群集控制器使用的网络设置了“静态 IP 低”和“静态 IP 高”。一旦我清除了这些字段，问题就消失了，它启动正常。或者更准确地说，我遇到了其他问题。
