VMware add hard drives under Linux

1. Add a hard disk to the settings of the virtual machine. setting, add disk, create a new virtual disk, SCSI set size, here to 3G; change the name, I use this hard drive to install Oracle, named ORADATA.VMDK 2. Formatting Hard disk.

2. [root@yaokj ~]# fdisk -l /dev/SDB
   
4. 
   
6. Disk /dev/sdb: 2147 MB, 2147483648 bytes
   
8. 255 heads, sectors/track, 261 cylinders
   
10. Units = cylinders of 16065 * 8225280 bytes
    
12. 
    
14. Disk/dev/sdb doesn ' t contain a valid partition table

To format the hard disk, there is no need to specify the partition type, the default Linux is available.

2. [root@yaokj ~]# fdisk /dev/SDB
   
4. 
   
6. Command (m for help): p

30. P
32. Partition Number (1-4): 1
    
34. First cylinder (1-261, default 1):
    
36. Using default Value 1
    
38. Last cylinder or +size or +sizem or +Sizek ( 1-261, default 261):
    
40. Using default Value 261
    
42. 
    
44. Command (m for help): p
    
46. 
    
48. Disk /dev/sdb: 2147 MB, 2147483648 bytes
    
50. 255 heads, sectors/track, 261 cylinders
    
52. Units = cylinders of 16065 * 8225280 bytes
    
54. 
    
56. Device Boot Start End Blocks Id System
    
58. /Dev/sdb1 1 261 2096451 Linux
    
60. 
    
62. Command (M for help): W
    The partition table has been altered!
    Calling IOCTL () to re-read partition table.
    
    

3. Creating a File system

[Email protected] ~]# MKFS.EXT3/DEV/SDB1
4. Mount the partition. Here we will mount Oracle in the/U01 directory.

2. [root@yaokj~] # Mount -t ext3 /dev/sdb1 /u01
   
4. [root@yaokj ~] # DF -H
   
6. Filesystem Size used Avail use% mounted on
   
8. /Dev/sda2 3. 9G 2. 4G 1. 3G% /
   
10. /Dev/sda1 46M 11M 33M% /Boot
    
12. None 252M 0 252M 0 /dev/SHM
    
14. /Dev/sda3 7. 0G 49M 6. 6G 1 /Home
    
16. /Dev/sdb1 2. 0G 36M 1. 9G 2% /u01
    
18. [root@yaokj ~] #

We see that the/DEV/SDB1 has been mounted to the/U01 directory.

After this reboot, you will have to mount the directory again. We write in the config file, and the next reboot is automatically mounted. Modify the Vi/etc/fstab partition table file

Add at end of file /dev/sdb1 /u01 ext3 defaults 0 0

Reboot .

A detailed description of the Fstab file. You can see the configuration and understanding of Fstab files in Linux.

Note: Because the data is re-mounted, the Oracle directory will be recreated and executed (otherwise Oracle would be error-included):

2.3 Creating a Directory

Mkdir-p/u01/app/

Chown-r oracle:oinstall/u01/app/

Chmod-r 775/u01/app/
