Problem: the link aggregation status on bond0 is abnormal.

Scenario: The test today found that eth0 was not successfully started. Although bond0 has been configured properly, the physical link of bond0 is detected.

# Ethtool bond0

Link State: Yes

# Ethtool eth0

Link State: No

# Ethtool eth1

Link State: No

Is it because the aggregation layer has done any operation that makes what we see illusory. There is no physical link at all.

 

Locking problem: Nic 1 is physically damaged and nic 2 is not connected to the vswitch.
