e2fsck：无法在 LogicalVolume 上设置超级块标志

Question

当我以正常模式或运行级别 1 启动我的机器时，它会引发以下错误并且我无法启动机器：

 checking filesystems  
/dev/MyGroup/LogVol00: UNEXPECTED INCONSISTENCY; RUN fsck MANNUALLY  
       (i.e., without -a or -p options)  

\*** An error occured 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):

我输入密码并运行fsckand e2fsck，但两者都给出了相同的错误格式，如下所示：

(Repair filesystem) 1 # fsck
fsck 1.39 (29-May-2006)

或者

(Repair filesystem) 1 # e2fsck -y /dev/MyGroup/LogVol00
e2fsck 1.39 (29-May-2006)
/dev/MyGroup/LogVol001: clean, 141289/1402144 files, 804207/1400832 blocks
e2fsck 1.39 (29-May-2006)
The filesystem size of the device is 131072 blocks
Either the superblock or the partition table is likely to be corrupt!

现在我决定使用备用超级块如下：

(Repair filesystem) 6 #dumpe2fs /dev/MyGroup/LogVol00 | grep -i superblock

通过alternative-superblock使用命令修复文件系统如下：

(Repair filesystem) 7 #e2fsck -f -b 8193 /dev/MyGroup/LogVol00

使用所有备用超级块后，我收到相同的错误消息，如下所示：

e2fsck 1.39 (29-May-2006)  
/dev/MyGroup/LogVol00: recovering journel  
e2fsck: unable to set superblock flags on /dev/MyGroup/LogVol00:

如何解决此类问题？
