强制卸载NFS挂载的目录 [英] Force unmount of NFS-mounted directory

问题描述

我在挂起的Linux机器上有一个NFS挂载目录.我试图强行卸下，但似乎不起作用:

I have an NFS-mounted directory on a Linux machine that has hung. I've tried to force an unmount, but it doesn't seem to work:

$ umount -f /mnt/data
$ umount2: Device or resource busy
$ umount: /mnt/data: device is busy

如果键入"mount"，则似乎目录已不再挂载，但是如果执行"ls /mnt/data"，则目录将挂起，并且如果尝试删除安装点，则会得到:

If I type "mount", it appears that the directory is no longer mounted, but it hangs if I do "ls /mnt/data", and if I try to remove the mountpoint, I get:

$ rmdir /mnt/data
rmdir: /mnt/data: Device or resource busy

除了重新启动计算机外，我还能做些什么吗?

Is there anything I can do other than reboot the machine?

推荐答案

您可以尝试延迟卸载:

umount -l
