更改ubuntu的挂载点

我的是给ubuntu的空间太少了`但是主要工程都是在home下，所以格式化了一个空间来作为home，然后挂载到/下

以root权限，在终端的窗口里输入命令，找到你要挂载的分区，这里以sda5为例

$ fdisk -l

Disk /dev/sda: 320.1 GB, 320072933376 bytes

255 heads, 63 sectors/track, 38913 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Sector size (logical/physical): 512 bytes / 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes

Disk identifier: 0xf517e314

   Device Boot      Start         End      Blocks   Id  System

/dev/sda1   *           1        5222    41945683+   7  HPFS/NTFS

/dev/sda2            5223        7712    19999744   83  Linux

/dev/sda3            7712        7961     1999872   82  Linux swap / Solaris

/dev/sda4            7962       38913   248621940    5  Extended

/dev/sda5            7962       17687    78124063+  83  Linux

/dev/sda6           17688       25520    62918541    7  HPFS/NTFS

/dev/sda7           25521       38913   107579241    7  HPFS/NTFS

这里可以看到/dev/sda5，这应该是我想挂载在home下的分区。察看sda5的UUID

$ ls -l /dev/disk/by-uuid

看一下sda5的UUID

总计 0

lrwxrwxrwx 1 root root 10 2011-04-03 16:06 3aa554c2-e8ea-4f35-819f-7cb4573c0d67 -> ../../sda5

lrwxrwxrwx 1 root root 10 2011-04-03 16:06 4E8091348091240D -> ../../sda7

lrwxrwxrwx 1 root root 10 2011-04-03 16:06 7b1c60be-8b84-4459-9bef-9559d9431447 -> ../../sda2

lrwxrwxrwx 1 root root 10 2011-04-03 16:06 8c5324bb-9e42-422d-b507-26bafa5ac7de -> ../../sda3

lrwxrwxrwx 1 root root 10 2011-04-03 16:06 AAA87F76A87F403D -> ../../sda6

lrwxrwxrwx 1 root root 10 2011-04-03 16:06 C478ECC978ECBAF6 -> ../../sda1

将sda5的UUID填到fstab关于home的挂载那一行。

$ vim /etc/fstab 
# /etc/fstab: static file system information.
#
# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name
# devices that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    nodev,noexec,nosuid 0       0
# / was on /dev/sda2 during installation
UUID=7b1c60be-8b84-4459-9bef-9559d9431447 /               ext4    errors=remount-ro 0       1
# /home was on /dev/sda5 during installation
UUID=3aa554c2-e8ea-4f35-819f-7cb4573c0d67 /home           ext4    defaults        0       2
# /windows was on /dev/sda6 during installation
# UUID=50C5-059A /windows        vfat    utf8,umask=007,gid=46 0       1
# swap was on /dev/sda3 during installation
UUID=8c5324bb-9e42-422d-b507-26bafa5ac7de none            swap    sw              0       0
另外，windows这个挂载点我不需要了，将fstab对应那几行用#号注掉。
恩``那就好了``

这里还顺带解决了开机之后差看不到windows分区的问题
