Linux下如何用fdisk新建分区

[日期:2013-03-14] 来源:51cto  作者:lfgwqc [字体: ]
fdisk磁盘分区工具
 
1.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)
 fdisk选中/dev/sdb 输入m所有基本选项都出现,输入n新建分区
 
Command (m for help): n
 Command action
    e  extended
    p  primary partition (1-4)linux
