首先，对新加入的硬盘格式化。
步骤1:
步骤2:
步骤3:
步骤4 格式化分区
步骤5:创建目录然后将该分区加挂到该目录下
[root@rac1 /]# mount /dev/sdb1 /u01
步骤6:修改/etc/fstab文件添加如下记录使系统每次重启后都能自动加载该分区
步骤7:
[root@rac1 /]#vi /etc/fstab
在文件的末尾填加如下内容
/dev/sdb1 /u01 ext3 defaults 1 2
说明:
若新加硬盘的时候选择了创建逻辑盘(即选择了e)的时候,格式话的时候会报如下错误:
Invalid argument passed to ext2 library while setting up superblock.
这是因为我们这里只创建了逻辑盘,没有创建逻辑分区,所以创建完逻辑盘后还需要创建逻辑分区:
The number of cylinders for this disk is set to 2088.
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)

如此便完成了linux下新硬盘的添加与分区、格式化等操作。
