cobbler在导入镜像时出错

问题描述

cobbler在导入镜像时报以下错误：

task started: 2018-06-06_125116_import
task started (id=Media import, time=Wed Jun  6 12:51:16 2018)
Exception occured: 'cobbler.cexceptions.CX'>
Exception value: 'Command failed'

查看日志文件，发现报以下错误：

Fri Jun  1 11:28:57 2018 - DEBUG | received on stderr: rsync: read errors mapping "/mnt/EFI/TRANS.TBL": Input/output error (5)

...

问题原因

1. 防火墙、selinux等确认是否关闭（我这里是已经关闭了的）
2. 确认镜像文件是否损坏，我这里就是镜像文件出了问题，换了一个新的镜像就导入OK了。
