如何解决过时的 nfs 句柄？

我注意到有一次，当我关闭我的家庭服务器，而我的桌面通过 NFS 连接时，我在进入我的主目录时不断收到“过时的 NFS 句柄警告”，这导致了在这些文件夹中查找的某些程序出现问题。

如何在不重新启动机器的情况下解决此问题？

Debian Squeeze/Wheezy

答案1

在 Debian Squeeze/Wheezy 上：

强制卸载本地挂载

umount -f /mnt/dir

然后重启nfs

/etc/init.d/nfs-common restart

答案2

试试这个 shell 脚本。对我来说效果很好：

#!/bin/bash
# Purpose:
# Detect Stale File handle and remove it
# Script created: July 29, 2015 by Birgit Ducarroz
# Last modification: --
#

# Detect Stale file handle and write output into a variable and then into a file
mounts=`df 2>&1 | grep 'Stale file handle' |awk '{print ""$2"" }' > NFS_stales.txt`
# Remove : ‘ and ’ characters from the output
sed -r -i 's/://' NFS_stales.txt && sed -r -i 's/‘//' NFS_stales.txt && sed -r -i 's/’//' NFS_stales.txt

# Not used: replace space by a new line
# stales=`cat NFS_stales.txt && sed -r -i ':a;N;$!ba;s/ /\n /g' NFS_stales.txt`

# read NFS_stales.txt output file line by line then unmount stale by stale.
#    IFS='' (or IFS=) prevents leading/trailing whitespace from being trimmed.
#    -r prevents backslash escapes from being interpreted.
#    || [[ -n $line ]] prevents the last line from being ignored if it doesn't end with a \n (since read returns a non-zero exit code when it encounters EOF).

while IFS='' read -r line || [[ -n "$line" ]]; do
    echo "Unmounting due to NFS Stale file handle: $line"
    umount -fl $line
done < "NFS_stales.txt"
#EOF

我通常会发出这些命令（如root）：

service nis restart
service autofs restart
service nfs restart
service portmap restart

您可能不需要所有这些，具体取决于您的系统的工作方式。
