systemd-fsck-root服務啟動失敗的解決辦法

今天半夜噹噹噹的被警告信吵醒，部落格主機突然掛點 😱🥶🙀 急忙連線SSH發現也連不上，改用VNC連上後發現機器已經進入了emergency mode 緊急情況模式～～囧 😣

See ‘systemctl status systemd-fsck-root.service’ for details.
[DEPEND] Dependency failed for /sysroot.
[DEPEND] Dependency failed for Initrd Root File System.
[DEPEND] Dependency failed for Reload Configuration from the Real Root.

第一行的提示systemd-fsck-root服務是指File System Check 檔案系統檢查，用下列兩種指令查詢系統記錄，果不其然是磁碟區有問題了 😱

• systemctl status systemd-fsck-root -l
• journalctl -xe

如圖所示，圖片中的紅字就是代表真的是磁碟區有問題，最壞的狀況就是壞軌或是硬碟掛了 🥶

• fsck failed with exit status 4.
• Failed to start File System Check on/dev/disk/OOXX

而在紅字的上方，/dev/vda1就是系統偵測到有問題的磁碟區，所以先使用fsck這個指令來做修復的動作～ 🙀

fsck -y /dev/vda1

接下來會刷刷刷的開始跑修復，直到最後看到FILE SYSTEM WAS MODIFIED就可以重開機了，呼～總算是暫時救回一命，暫時輕鬆一些了，不過這也提醒我要搬家了～ 囧 🤖🤓🤖
