基本步骤：分区——格式化——挂载——写入文件
1、首先用fdisk -l命令查看添加的硬盘名称，可以看到sdb为新增的硬盘
| [root@oracle ~]# fdisk -l 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 Disk /dev/sda: 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: 0x0006b59c Device Boot Start End Blocks Id System /dev/sda1 * 1 39 307200 83 Linux Partition 1 does not end on cylinder boundary. /dev/sda2 39 2358 18631680 83 Linux /dev/sda3 2358 2611 2031616 82 Linux swap / Solaris |
2、进行分区，输入m查看提示
| [root@oracle ~]# 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 0x09f38795. 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) |
分析：主要参数的解析
1. 输入 m 显示所有命令列示。
2. 输入 p 显示硬盘分割情形，打印分区表。
3. 输入 a 设定硬盘启动区。
4. 输入 n 创建新的硬盘分割区。
4.1. 输入 e 硬盘为[延伸]分割区(extend)。
4.2. 输入 p 硬盘为[主要]分割区(primary)。
5. 输入 t 改变硬盘分割区属性。
-
t:分区系统id号
L:82:linux swap
83:linux
86：NTFS window分区
6. 输入 d 删除硬盘分割区属性。
7. 输入 q 结束不存入硬盘分割区属性。
8. 输入 w 结束并写入硬盘分割区属性
3、输入n创建新的硬盘分区——输入p创建主分区——输入1设置一个分区——回车——回车（默认全部空间）
