linux mount 沒反應 後來出現 mount.nfs input/output error

 有一台linux主機在重開機後要重新mount其他機器的分享資料夾，執行執令後，畫面上沒任何反應。

過了一下子才會出現 mount.nfs input/output error，這是因為 /etc/init.d/portmap 這個服務沒有啟動的關係，

 先 執行/etc/init.d/portmap status， 確認該服務是stop。

接著用執行啟用的指令/etc/init.d/portmap start，就可以再執行mount的動作了。

A Linux host fails to mount a shared folder from another machine after a reboot. After executing the mount command, the screen is blank.

After a while, an error message "mount.nfs input/output error" appears. This is because the service "/etc/init.d/portmap" is not running.

First, execute the command "/etc/init.d/portmap status" to confirm that the service is stopped.

Then, execute the command "/etc/init.d/portmap start" to start the service. After that, you can mount the shared folder again.
