[root@localhost ~]# cobbler check
The following are potential configuration items that you may want to fix:

1 : debmirror package is not installed, it will be required to manage debian deployments and repositories # debian相关 2 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them # fence设备相关，不需要

Restart cobblerd and then run 'cobbler sync' to apply changes.
