从查询结果看出,多了一个/dev/sdb的盘
2. 用fdisk 对/dev/sdb 进行分区
[iyunv@db1 /]# fdisk /dev/sdb
Command (m for help): n
Command action
e extended
p primary partition (1-4)
p
Partition number (1-4): 1
First cylinder (1-652, default 1):
Using default value 1
Last cylinder or +size or +sizeM or +sizeK (1-652, default 652):
Using default value 652
Command (m for help): w
The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.

如果创建完之后,/proc/partitions 查看不到对应的分区,使用parprobe 命令刷新一下就可以了:
[iyunv@web1 ~]# cat /proc/partitions
major minor #blocks name
8 0 175825944 sda
8 1 1020096 sda1
8 2 30716280 sda2
8 3 8193150 sda3
[iyunv@web1 ~]# partprobe /dev/sda
[iyunv@web1 ~]# cat /proc/partitions
major minor #blocks name
[iyunv@db1 /]# mkfs -t ext3 /dev/sdb1

4. 创建目录 并将 /dev/sdb1 挂在到该目录下
[iyunv@db1 /]# ls
backup dev initrd media opt sbin sys usr
bin etc lib misc proc selinux tftpboot var
boot home lost+found mnt root srv tmp
[iyunv@db1 /]# mkdir /u01
[iyunv@db1 /]# ls
backup dev initrd media opt sbin sys u01
bin etc lib misc proc selinux tftpboot usr
boot home lost+found mnt root srv tmp var
[iyunv@db1 /]# mount /dev/sdb1 /u01
