linux强制卸载

Some time, fails to unmount a filesystem reporting “device is busy”. I understand that this helps avoid data lost by disallowing unmouting a filesystem when it is being used.

有时， 无法卸载报告“设备正忙”的文件系统。 我了解这可以避免在使用文件系统时取消对其进行mounting，从而避免数据丢失。

But for some situations, I am sure there is something wrong happened or I care not data lost, such as a NFS mounting while the NFS is dead and will never be back. Under these kinds of situations, how do I force to unmount a filesystem?

但是在某些情况下，我确定发生了某些错误，或者我不在乎数据是否丢失，例如在NFS 死机且永远不会恢复的情况下进行NFS挂载。 在这种情况下，如何强制卸载文件系统？
