最近發現一台RHEL 5.1伺服器的/var/log/message出現這樣的錯誤訊息:

Nov 21 14:19:01 localhost restorecond: Will not restore a file with more than one hard link (/etc/resolv.conf) No such file or directory
Nov 21 16:21:51 localhost restorecond: Will not restore a file with more than one hard link (/etc/resolv.conf) No such file or directory
Nov 22 09:39:47 localhost restorecond: Will not restore a file with more than one hard link (/etc/resolv.conf) No such file or directory
Nov 22 09:40:39 localhost restorecond: Will not restore a file with more than one hard link (/etc/resolv.conf) Invalid argument

因為在CentOS/RHEL中/etc/sysconfig/networking/profiles/default/resolv.conf是hard link到/etc/resolv.conf，我們可以透過下列指令找出全部的hard link

find / -xdev -samefile /etc/resolv.conf

輸出大致如下:

/etc/sysconfig/networking/profiles/default/resolv.conf

/etc/resolv.conf

解法，用root權限依序執行下列步驟即可:


rm /etc/sysconfig/networking/profiles/default/resolv.conf

restorecon /etc/resolv.conf

ln /etc/resolv.conf /etc/sysconfig/networking/profiles/default/resolv.conf
