Centos系统中如何挂载第二块硬盘,centos挂载

一、检测硬盘能否被识别

# fdisk -l

Disk /dev/sda: 36.7 GB, 36703934464 bytes

255 heads, 63 sectors/track, 4462 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System

/dev/sda1 * 1 261 2096451 83 Linux

/dev/sda2 262 783 4192965 83 Linux

/dev/sda3 784 1305 4192965 83 Linux

/dev/sda4 1306 4462 25358602+ 5 Extended

/dev/sda5 1306 1827 4192933+ 83 Linux

/dev/sda6 1828 2088 2096451 82 Linux swap

/dev/sda7 2089 4462 19069123+ 83 Linux

Disk /dev/sdb: 36.7 GB, 36748945408 bytes

255 heads, 63 sectors/track, 4467 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System

/dev/sdb1 * 1 509 4088511 83 Linux

/dev/sdb2 510 2430 15430432+ 83 Linux

/dev/sdb3 2431 2557 1020127+ 82 Linux swap

/dev/sdb4 2558 4467 15342075 f W95 Ext'd (LBA)

/dev/sdb5 2558 2811 2040223+ 83 Linux

/dev/sdb6 2812 3830 8185086 83 Linux

/dev/sdb7 3831 4467 5116671 83 Linux

/dev/sdb 说明已经识别出第二块硬盘

二、挂载硬盘

1、在本地硬盘中临时创建一个目录

#mkdir /opt/data/tmp1

2、挂载第二块硬盘中的一个分区/dev/sdb1到tmp1

#mount /dev/sdb1 /opt/data/tmp1

3、查看是否被挂载

# df -h

Filesystem Size Used Avail Use% Mounted on

/dev/sda1 2.0G 141M 1.8G 8% /

none 1014M 0 1014M 0% /dev/shm

/dev/sda2 4.0G 1.8G 2.0G 47% /opt

/dev/sda7 18G 168M 17G 1% /opt/data

/dev/sda5 4.0G 1.4G 2.4G 37% /usr

/dev/sda3 4.0G 2.1G 1.8G 55% /var

/dev/sdb1 3.9G 1.4G 2.3G 38% /opt/tmp/tmp1

三、卸载硬盘

#umount /dev/sdb1
