安装 USB 时出现“安装：错误的文件系统类型..”错误

我在尝试在 Raspberry Pi (Wheezy) 上安装 USB 驱动器时遇到了困难。我已经重新格式化它（ext4）并尝试重新安装它/media/owncloud（如下sudo chown -R pi:pi /media/owncloud），但安装时遇到错误：

pi@raspberrypi /media $ sudo mount /dev/sda1 /media/owncloud -o uid=pi,gid=pi -t ext4
mount: wrong fs type, bad option, bad superblock on /dev/sda1,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

pi@raspberrypi /media $ dmesg | tail

知道是什么原因造成的吗？我在其他地方尝试了一种解决方案（sudo e2fsck -f -b 32768 -y /dev/sda1），结果是：

/dev/sda1: ***** FILE SYSTEM WAS MODIFIED *****
/dev/sda1: 11/493856 files (0.0% non-contiguous), 68109/1974271 blocks

..但没有解决问题。有任何想法吗？

答案1

你不能-o uid=pi,gid=pi与ext4;一起使用以下应该有效：

sudo mount /dev/sda1 /media/owncloud -t ext4

uid和选项gid适用于本身不跟踪所有权的文件系统（例如 FAT）。ext4是一个 POSIX 文件系统，并保留自己的有关文件所有权的信息，因此它不需要（也不能使用）uid和gid选项。
