标题: 在9i中添加磁盘挂载点

1、在虚拟机中添加一块磁盘
2、在root用户下fdisk -l查看磁盘情况并且找到新添加的未挂载的硬盘
3、格式化添加到分区
[root@bogon ~]# fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.

Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

Command (m for help): m
Command action
   a   toggle a bootable flag
   b   edit bsd disklabel
   c   toggle the dos compatibility flag
   d   delete a partition
   l   list known partition types
   m   print this menu
   n   add a new partition
   o   create a new empty DOS partition table
   p   print the partition table
   q   quit without saving changes
   s   create a new empty Sun disklabel
   t   change a partition's system id
   u   change display/entry units
   v   verify the partition table
   w   write table to disk and exit
   x   extra functionality (experts only)

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.

4、查看添加到分区以后的新名称
[root@bogon ~]# fdisk -l

Disk /dev/sda: 21.4 GB, 21474836480 bytes
255 heads, 63 sectors/track, 2610 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id System
/dev/sda1   *           1          13      104391   83 Linux
/dev/sda2              14         274     2096482+ 82 Linux swap / Solaris
/dev/sda3             275        2610    18763920   83 Linux

Disk /dev/sdb: 5368 MB, 5368709120 bytes
255 heads, 63 sectors/track, 652 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/sdb1 1 652 5237158+ 83 Linux

5、创建文件系统，为磁盘创建格式：
[root@bogon ~]# mkfs.ext3 /dev/sdb1
mke2fs 1.39 (29-May-2006)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
655360 inodes, 1309289 blocks
65464 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=1342177280
40 block groups
32768 blocks per group, 32768 fragments per group
16384 inodes per group
Superblock backups stored on blocks:
32768, 98304, 163840, 229376, 294912, 819200, 884736

Writing inode tables: done
Creating journal (32768 blocks): done
Writing superblocks and filesystem accounting information: done

This filesystem will be automatically checked every 22 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.

6、创建存储数据文件并执行挂载
[root@bogon ~]# mkdir /oradata
[root@bogon ~]# mount /dev/sdb1 /oradata

7、给oradata赋权限
[root@bogon ~]# chown -R oracle:oinstall /oradata

8、oracle用户下在oradata下面以实例名创建目录
[oracle@bogon ~]$ cd /oradata
[oracle@bogon oradata]$ mkdir orcl
[oracle@bogon oradata]$ ls
orcl

写的比较直观,

但这里说法:

6、创建存储数据文件并执行挂载
[root@bogon ~]# mkdir /oradata
[root@bogon ~]# mount /dev/sdb1 /oradata

应该是创建挂载点,并进行挂载.
