  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)
