最近要搬家，于是把那块Hikari上的固态盘装到Lolipop上了。
后来急需一个文件，发现那块分区死都挂载不上。
原本我的硬盘(sda)是这么分配的：
- /dev/sda1 Linux系统盘
- /dev/sda2 VM直通盘
- /dev/sda2p1 EFI分区
- /dev/sda2p2 WinOS
结果现在我只能挂载sda，sda2p提示找不到设备。
root@Lolipop:/mnt/120G# mount /dev/sda2p2 ntfs
mount: /mnt/120G/ntfs: special device /dev/sda2p2 does not exist.那么直接挂载sda2呢？
root@Lolipop:/mnt/120G# mount /dev/sda2 ntfs
mount: /mnt/120G/ntfs: wrong fs type, bad option, bad superblock on /dev/sda2, missing codepage or helper program, or other error.emmm....
Google上查了一下，发现有类似问题，但是没有解决方案。
后来到telegram上问了一下dalao，解决了这个问题。
/dev/mapper
似乎这个地方是专门存放子分区文件系统的
很不巧，ls了一下，我这边并没有相关文件。
root@Lolipop:/dev/mapper# ll
总用量 0所以，我们得手动添加
KPartx
kpartx - Create device maps from partition tables
这个软件似乎是专门来创建分区表的
Debian默认没有带，所以得apt装一个
然后使用它的-a参数就可以了
root@Lolipop:/dev/pts# kpartx -a /dev/sda2
root@Lolipop:/dev/pts# fdisk -l

出现了,sda2p2!
NTFSFix
现在还等什么？赶紧挂载把！
root@Lolipop:/mnt/120G/# mount /dev/mapper/sda2p2 n
The disk contains an unclean file system (0, 0).
Metadata kept in Windows cache, refused to mount.
Falling back to read-only mount because the NTFS partition is in an
unsafe state. Please resume and shutdown Windows fully (no hibernation
or fast restarting.)
Could not mount read-write, trying read-only
^C等等等等！为什么只能挂只读了？？
emm，上次没好好关Windows虚拟机就这样了...
直接ntfsfix！
root@Lolipop:/mnt/120G/ntfs# ntfsfix /dev/mapper/sda2p2
