node0: 

error: configuration check-out failed

node1: 

error: remote commit-configuration failed on node0

error: commit failed

Solution

The error message was because the device was in cluster status. When you use the "set" command to add the license key then commit the configuration, this set command need to commit on both nodes. However, when commit on node 0, the serial number of node0 cannot match with license's device serial number. So it will check-out fail as serial number mismatch.

​So you can use "request system licence add terminal​" to resolve this issue
