  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。  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)
