请教关于cvsup时出现的错误问题

在cvsup时出下面错误：
#cvsup /root/cvsup/ports-supfile
Connected to cvsup.FreeBSDChina.org
Updating collection ports-all/cvs
Delete ports/INDEX
Delete ports/INDEX-5
TreeList failed: Read failure from "/usr/sup/ports-all/checkouts.cvs:.": Input/output error
是什么原因造成，怎么解决？

你用这个命令试一下啊？？

#cvsup -g -L 2 /root/cvsup/ports-supfile


你可以打开PORTS-SUPFILE这一个文件看一看

#cvsup -g -L 2 /root/cvsup/ports-supfile
