采取的步骤：
*使用 fdisk 删除现有根分区并从同一块开始创建一个新的根分区 (PV)
*使用 fdisk 添加了“a”标志，使其可启动，因为 /boot 位于根分区下
重新启动后，我卡在 GRUB 屏幕上，并显示错误“尝试在磁盘 'hd0' 之外读取或写入”
使用实时 USB 后，这是我当前的分区表：
mint@mint ~ $ sudo fdisk -l
Disk /dev/sda: 320.1 GB, 320072933376 bytes
255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disk identifier: 0x0008fb69
Device Boot Start End Blocks Id System
/dev/sda1 * 2048 41945087 20971520 83 Linux
/dev/sda2 609040382 625141759 8050689 5 Extended
Partition 2 does not start on physical sector boundary.
/dev/sda5 609040384 625141759 8050688 82 Linux swap / Solaris
我不确定为什么会收到此错误，因为我认为分区不必是连续的。
mint@mint ~ $ sudo fsck /dev/sda1
fsck from util-linux 2.20.1
e2fsck 1.42.9 (4-Feb-2014)
Error reading block 37781504 (Invalid argument). Ignore error<y>? yes
Force rewrite<y>? no
Superblock has an invalid journal (inode 8).
Clear<y>? no
fsck.ext4: Illegal inode number while checking ext3 journal for /dev/sda1
/dev/sda1: ********** WARNING: Filesystem still has errors **********
我打算在调整分区大小后使用 resize2fs 重新调整文件系统的大小，但是来自 fsck 的这个错误似乎我应该首先处理这个问题。查看解决方案后，似乎如果我清除超级块，文件系统将丢失其日志并变成外部2。我不确定发生了什么事，希望得到一些建议。
谢谢。
