Linux利用fdisk工具建立分区的方法

  当Linux系统硬盘还有不少空间的时候,我们能够使用fdisk工具对系统进行分区,以满足个人需求,那么fdisk工具要如何使用呢?下面小编就给大家介绍下Linux使用fdisk建立分区的方法,感兴趣的朋友可以来了解下。

 Linux利用fdisk工具建立分区的方法

  首先查看硬盘信息

  fdisk -l 如果有硬盘有剩余空间就可以对其进行分区

  [root@bogon 桌面]# fdisk -l

  Disk /dev/sda: 85.9 GB, 85899345920 bytes

  255 heads, 63 sectors/track, 10443 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: 0x000471ad

  Device Boot Start End Blocks Id System

  /dev/sda1 * 1 26 204800 83 Linux

  Partition 1 does not end on cylinder boundary.

  /dev/sda2 26 3851 30720000 83 Linux

  /dev/sda3 3851 4106 2048000 82 Linux swap / Solaris

  /dev/sda4 4106 10444 50912256 5 Extended

  /dev/sda5 4106 10444 50911232 83 Linux

  Disk /dev/sdb: 21.5 GB, 21474836480 bytes

  255 heads, 63 sectors/track, 2610 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: 0x00000000

  #从上面看出/dev/sda空间已经用完了,/dev/sdb没有使用。

  下面我们对/dev/sdb 进行分区

  [root@bogon 桌面]# fdisk /dev/sdb

  Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel

  Building a new DOS disklabel with disk identifier 0xfaa2aa49.

  Changes will remain in memory only, until you decide to write them.

  After that, of course, the previous content won‘t be recoverable.

  Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

  WARNING: DOS-compatible mode is deprecated. It’s strongly recommended to

  switch off the mode (command ‘c’) and change display units to

  sectors (command ‘u’)。

  Command (m for help): m

  Command action

  a toggle a bootable flag

  b edit bsd disklabel

  c toggle the dos compatibility flag

  d delete a partition

  l list known partition types

  m print this menu

  n add a new partition

  o create a new empty DOS partition table

  p print the partition table

  q quit without saving changes

  s create a new empty Sun disklabel

  t change a partition‘s system id

  u change display/entry units

  v verify the partition table

  w write table to disk and exit

  x extra functionality (experts only)
