Debian Squeeze / Wheezyの場合:
ローカルマウントを強制的にマウント解除します
umount -f /mnt/dir
次にnfsを再起動します
/etc/init.d/nfs-common restart
このシェルスクリプトを試してください。私にとってはうまくいきます:
#!/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
