Linux上挂载新硬盘详解

Linux上挂载新硬盘详解

 

（一）查看硬盘分布和对新硬盘进行分区

[root@cncmail data1]# fdisk -l ## 这里是查看目前系统上有几块硬盘

Disk /dev/sda: 36.4 GB, 36401479680 bytes
255 heads, 63 sectors/track, 4425 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/sda1 * 1 255 2048256 83 Linux
/dev/sda2 256 1530 10241437+ 83 Linux
/dev/sda3 4296 4425 1044225 82 Linux swap
/dev/sda4 1531 4295 22209862+ f Win95 Ext'd (LBA)
/dev/sda5 1531 2805 10241406 83 Linux
/dev/sda6 2806 4295 11968393+ 83 Linux

Partition table entries are not in disk order

Disk /dev/sdb : 36.7 GB, 36703918080 bytes ## 这里发现/dev/sdb，容量36.7G，切未被分区
255 heads, 63 sectors/track, 4462 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/sdc doesn't contain a valid partition table
[root@linux root]# fdisk /dev/sdb ## 接下去就对/dev/sdb分区进行分区

The number of cylinders for this disk is set to 4462.
There is nothing wrong with that, but
