Vbox fdisk does not display the added hard disk Solution

 

 

The disk we added cannot be viewed using the fdisk command:

 

[Root @ Rac1 ~] # Fdisk-l

 

Disk/dev/SDA: 32.2 GB, 32212254720 bytes

255 heads, 63 sectors/track, 3916 Cylinders

Units = cylinders of 16065*512 = 8225280 bytes

Sector size (logical/physical): 512 bytes/512 bytes

Run start_udev manually and run the fdisk command to view the disk.

 

It is estimated that there is a problem during udev startup.

 

View the udev service status:

[Root @ Rac1 ~] # Service udev-post status

[Root @ Rac1 ~] # Chkconfig udev-post -- list

Udev-post 0: off 1: On 2: On 3: On 4: On 5: on 6: Off

[Root @ Rac1 ~] # Service udev-post Start

Retrigger failed udev events [OK]

 

 

Note:

I am using Oracle Linux, so the udev service is: udev-post. If it is RedHat, the corresponding service is: udev

 

 

If you do not study this issue in depth, add start_udev to the startup Item to ensure normal use.

# This script will be executed * after * allthe other init scripts.

# You can put your own initialization stuffin here if you don't

# Want to do the full sys V style initstuff.
