昨晚把兩塊硬盤組成可擴容的lvm盤,掛載信息寫入到了**/etc/fstab**中。今天發現機器莫名其妙的重啓過,更糟糕的是沒法進入系統,屏幕上出現以下錯誤:cdn
you are in emergency mode. after logging in, type "journalctl -xb" to view system logs, "systemctl reboot" to reboot, "systemctl default" or ^d to try again to boot into default mode. cannot open access to console, the root account is locked. see sulogin(8) man page for more details. press enter to continue.

按回車系統試圖正常啓動,惋惜最終仍是失敗。斷電重啓屢次不能解決這個問題。blog
根據網上信息,大概是fstab信息有問題,致使**/boot**分區和根目錄沒法正常加載。因而和 重置密碼 文中同樣操做,init=/bin/sh
進入root環境。rem
先將/boot分區從新掛載:get
mount -o remount,rw /dev/mmcblk0p1 /boot
提示boot分區並未加載。用ls /boot
查看,空空如也。因而先掛載:mount /dev/mmcblk0p1 /boot
,再次用ls
查看,OK問題解決。cmd
接着從新掛載根目錄:mount -o remount,rw /dev/mmcblk0p2 /
。根目錄可寫後,編輯**/etc/fstab**文件,將引發問題的掛載點註釋掉。raspberry-pi
而後執行exec /sbin/init
啓動系統,此次終於正常進入系統了。it
按慣例,啓動後把**/boot/cmdline.txt**文件中的init=/bin/sh
刪除,避免下次又進入root環境。
