当我安装时/dev/VolGroup/lv_home出现错误：
[root@localhost VolGroup]# mount /dev/VolGroup/lv_home /home/

*** ext3 journal has been deleted - filesystem is now ext2 only ***
Superblock has_log flag is clear, but a log inode is present.
Clear <y>? Yes

The physical size of the device is 26214400 block s
Either the super block or the partition table is likely to be corrupt!

你看我试过了fsck -t ext4 /dev/mapper/VolGroup-lv_home但还是不行。
我的系统是CentOS 6.8。

答案1
您最近是否已将此分区迁移到新磁盘？或者调整同一磁盘上现有分区的大小？在我看来，文件系统元数据与底层硬件不兼容，这与由于某种原因而更改的硬件是一致的（这是完全合法的事情 - 你只需正确地执行它）。
如果你可以承受丢失数据的损失，我会简单地mkfs /dev/VolGroup/lv_home结束它。
更好的办法是在移动到新卷之前缩小文件系统，然后将其扩展以适应 - 如果还不算太晚，请执行此操作。
否则，如果你想保留数据，首先要拍摄分区的映像，以防出现问题：
dd if=/dev/VolGroup/lv_home of=/var/tmp/home.img bs=65534
接下来再次运行 fsck，但是当您收到提示时Interrupt?说“否” - 您想要完成 fsck，而不是中断它。当它运行完成时，fsck为了安全起见，再次运行，然后尝试安装驱动器。让我们知道事情进展如何。
