在 debian9 上使用 systemd 設置網橋時出現太多符號連結錯誤
重新啟動後主機無法訪問,我在日誌中看到此錯誤
vmbr0: Could not join netdev: Too many levels of symbolic links
我真的不知道是什麼原因造成的,我在 Google 上找不到任何東西Dec 27 20:31:30 host8 systemd-networkd[448]: vmbr0: netdev ready Dec 27 20:31:30 host8 systemd-networkd[448]: Enumeration completed Dec 27 20:31:30 host8 systemd-networkd[448]: eth0: Renamed to eno1 Dec 27 20:31:30 host8 systemd-networkd[448]: vmbr0: Could not join netdev: Too many levels of symbolic links Dec 27 20:31:30 host8 systemd-networkd[448]: vmbr0: Failed Dec 27 20:31:30 host8 systemd-networkd[448]: eno1: IPv6 disabled for interface: Success Dec 27 20:31:30 host8 systemd-networkd[448]: eno1: Gained carrier
這是我的網橋設置:
# /etc/systemd/network/50-default.network [Match] MACAddress=a4:bf:01:26:XX:XX [Network] Bridge=vmbr0

看起來您正在嘗試將乙太網介面的 MAC 地址複製到新創建的網橋。
網橋提供了分配的 MAC 地址,但現在您有兩個具有該 MAC 地址的介面,物理介面
eno1
和網橋vmbr0
。因此,在
50-default.network
處理時,它會嘗試將與vmbr0
給定 MAC 地址匹配的每個介面分配給網橋。不幸的是vmbr0
也有這個地址,所以 systemd-networkd 不能分配vmbr0
為它自己的介面!
50-default.network
要解決此問題,請按名稱而不是 MAC 地址指定所需的乙太網介面。[Match] # Remove me # MACAddress=a4:bf:01:26:XX:XX Name=eno1 [Network] Bridge=vmbr0
