如何在linux系统中增加一块硬盘,并且格式化它呢:
[root@localhost dev]# fdisk /dev/sdb
The number of cylinders for this disk is set to 5221.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
Command (m for help): p
Disk /dev/sdb: 42.9 GB, 42949672960 bytes
255 heads, 63 sectors/track, 5221 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

The partition table has been altered!
Calling ioctl() to re-read partition table.
WARNING: Re-reading the partition table failed with error 16: 设备或资源忙.
The kernel still uses the old table.
The new table will be used at the next reboot.
Syncing disks.

分区完成!
(4)修改分区表
vim /etc/fstab
在最后加上一行:
/dev/sdb5 /sdb_one ext3 defaults 0 0
使用标签:
LABEL=/sdb5_label_hw /sdb_one ext3 defaults 0 0
(5)为分区设置标签
e2label /dev/sdb5 /sdb5_label_hw
注意:设置完成之后,最好reboot,否则使用mount进行挂载的时候,无法显示其中的内容,必须先进入文件夹,然后再退出,才能看到。
查看挂载情况,运行df -l
