MAAS 節點拒絕 DHCP 指派給它的 IP 位址

我正在嘗試在測試環境中配置 MAAS 和 Juju。我的 MAAS 區域和叢集控制器位於具有兩個 NIC 的單一電腦上。 eth1 連接到可存取網際網路的 LAN； IP 為 192.168.181.32。 eth0 是專用網路。我已將其配置為使用 192.168.212.0/24。

MAAS 設定為管理 eth0 上的 DHCP 和 DNS。我已向叢集新增了 3 個節點，所有節點均報告狀態為「就緒」。然而，當我嘗試引導 Juju 時，一切都變糟了：

> 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

到目前為止，一切都很好。這雲端2節點啟動並連接到 PXE，但隨後我開始收到：

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...

我的叢集控制器上的系統日誌顯示：

Oct 17 11:58:43 maas-master dhcpd: DHCPNAK on 192.168.212.6 to 08:00:27:1d:ea:91 via eth0

看起來節點獲得了 192.168.212.8 地址，並用它來下載內核和 initrd，但是一旦內核啟動並初始化節點上的 eth0 接口，它就拒絕接受 212.8 地址，並堅持使用212.6 地址，DHCP 伺服器不想給它。

有任何想法嗎？

我遇到了與此類似的問題，但不完全相同。我追蹤到為叢集控制器使用的網路設定了「靜態 IP 低」和「靜態 IP 高」。一旦我清除了這些字段，問題就消失了並且可以正確啟動。或者，更準確地說，我繼續解決其他問題。
