过程：通过命令提示符检查同步进度

  1. To list available logs before tailing, run the following command:

    mgrctl exec -ti -- ls /var/log/rhn/reposync/

  2. At the command prompt on the SUSE Multi-Linux Manager container host, as root, check the synchronization of a channel log file:

    mgrctl exec -ti -- tail -f /var/log/rhn/reposync/<channel-label>.log

  3. 每个子通道在同步过程中会生成自身的日志。您需要检查所有基础通道和子通道日志文件，以确保同步完成。
