linux如何挂载swap分区,Linux挂载新硬盘和创建Swap分区的方法

Liunx添加新硬盘其实和Windows的操作一样，但一个是图形化操作，另一个是命令行操作，不过步骤是一样，下面就动手演示和讲解

Linux挂载新硬盘

1、查看硬盘信息

命令：fdisk -l

[root@center ~]# fdisk -l

Disk /dev/vda: 21.5 GB, 21474836480 bytes #第一块硬盘的信息和分区信息

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: 0x0003a7b4

Device Boot Start End Blocks Id System

/dev/vda1 * 1 2611 20970496 83 Linux

Disk /dev/vdb: 107.4 GB, 107374182400 bytes #第二块硬盘的信息和分区信息

16 heads, 63 sectors/track, 208050 cylinders

Units = cylinders of 1008 * 512 = 516096 bytes

Sector size (logical/physical): 512 bytes / 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes

Disk identifier: 0x00000000

2、创建新硬盘分区

命令：fdisk /dev/vdb

[root@center ~]# fdisk /dev/vdb

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

Building a new DOS disklabel with disk identifier 0x1e694286.

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

After that, of course, the previous content won't be recoverable.
