问题描述
# mount –t ntfs /dev/sdc1 /mnt/usb2
mount: unknown filesystem type ‘ntfs’
原因：系统无法识别ntfs格式分区
解决办法
编译安装ntfs-3g。在 ntfs-3g 网站，下载最新稳定版软件包。
编译安装 ntfs-3g：
wget https://tuxera.com/opensource/ntfs-3g_ntfsprogs-2015.3.14.tgz
tar zxvf ntfs-3g_ntfsprogs-2015.3.14.tgz
cd ntfs-3g-2011.1.15
./configure
make
make install
重新挂载成功！
mount -t ntfs-3g /dev/sdc1 /mnt/usb2
基础知识
mount 命令
# man mount
看到如下：
All files accessible in a Unix system are arranged in one big tree, the file hierarchy, rooted at /. These files can be spread out over several devices. The mount command serves to attach the filesystem found on some device to the big file tree. Conversely, the umount(8) command will detach it again.
The standard form of the mount command, is
mount -t type device dir
This tells the kernel to attach the filesystem found on device (which is of type type) at the directory dir. The previous contents (if any) and owner and mode of dir become invisible, and as long as this filesystem remains mounted, the pathname dir refers to the root of the filesystem on device.
