wangzc2009 写了：/etc/fstab里面看看，把相关的东西前加#注释掉。
linux比较讲究权限管理。你使用的不是root权限的账户。所以没办法。

以下这么多，那个是我要改的呢，帮忙看看，谢谢

# Use 'vol_id --uuid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
