Appear in the NFS client mount rpc sharing service when the problem
[root@lnmp02 ~]# mount -t nfs 192.168.20.6:/data /mnt
mount.nfs: Stale file handle
The reason is that when the client-side mount on a directory server side, if the server-side turn up the directory unshare or delete, then this error will occur at the client. I really want to remove the front over the NFS server / data directory, so when re-mount the emergence of this problem. So how should you do it?
Solution:
其实解决办法很简单，就是在client上把那个文档umount掉。可是其实做起来很难，因为经常会得到 is busy的错误。
I just learned a command can solve this problem in watching the video of when the old boy linux
umount
[root@lnmp02 ~]# umount -lf /mnt
[root@lnmp02 ~]# mount -t nfs 192.168.20.6:/data /mnt
[root@lnmp02 ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda3 18G 1.2G 16G 8% /
tmpfs 504M 0 504M 0% /dev/shm
/dev/sda1 190M 48M 132M 27% /boot
192.168.20.6:/data 18G 16G 1.2G 8% / mnt
-lf / mnt
This way it is successfully resolved
