linux啟動系統時UNEXPECTED INCONSISTENCY報錯

啟動系統時，出現以下錯誤。

這意味著確認檔案系統時發現了問題，在這裡介紹一下修複檔案系統錯誤的方法。

Checking filesystems

/12: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
            (i.e., without -a or -p options)

*** An error occurred during the file system check.
*** Dropping you to a shell; the system will reboot
*** when you leave the shell.
Give root password for maintenance
(or type Control-D to continue):

根據提示輸入root使用者的密碼。

Give root password for maintenance
(or type Control-D to continue):　<-輸入root使用者的密碼

會開機檔案系統修複指令碼，然後利用mount命令確認需要修複的硬碟的區分。

(Repair filesystem) 1 # mount
/dev/hda6 on / type ext3 (rw) <-在這裡/dev/hda6是需要修複的硬碟

使用fsck命令進行修複，這時用-t選項指定檔案系統種類及版本。
會出現多次確認資訊，都輸入Enter(即Yes)。

(Repair filesystem) 2 # fsck -t ext3 /dev/hda6　開始修複
fsck 1.39 (29-May-2006)
e2fsck 1.39 (29-May-2006)
/12 contains a file system with errors, check forced.
Pass 1: Checking inodes, blocks, and sizes

  Clear? 　<-Enter

Inode 97249, i_blocks is 8, should be 0.
  Fix? 　<-Enter

Inodes that were part of a corrupted orphan linked list found.
  Fix? 　<-Enter

Inodes 1855559 was part of the orphaned inode list.  FIXED.

Deleted inode 1856596 has zero dtime.
  Fix? 　<-Enter
（省略）
Extended attribute block 1868847 has reference count 131,

/12: ***** FILE SYSTEM WAS MODIFIED *****
/12: ***** REBOOT LINUX *****
/12: 107499/2560864 files (1.5% non-contiguous),
 936536/2560351 blocks
(Repair filesystem) 3 # exit　<-退出修複模式

檔案系統的修複結束之後重啟系統，一般情況下都能修複成功，萬一修複失敗的話，就需要從系統備份進行恢複。

# reboot
