New Hard Disks added to Ubuntu

From http://blog.csdn.net/ymj7150697/article/details/5810683

1. Disable Ubuntu In the VM, add a new hardware device in "Settings", select hard disk, and click Next.

2. Select hard disk type. You can select ide or SCSI. Select SCSI here.

3. Select the location of the new virtual disk and name it ubuntu2.vmdk.

4. Set the hard disk size. Select allocate all disk space now. If this option is not selected, the hard disk is relatively small at the beginning. However, as the hard disk reads and writes access, the virtual hard disk files will become larger and larger. After this option is selected, the virtual hard disk is fixed to the selected 5g space and will not increase. Click Finish to create a new hard disk.

5. Start Ubuntu and log on as the root user.
Enter fdisk-L on the terminal.

Disk/dev/SDB doesn' t contain a valid Partition Table
----------------------------------------------------------------------------

Here we can see that/dev/SDB is the newly added hard disk, and we need to partition the new hard disk.
Enter fdisk/dev/SDB on the terminal
Enter m to view the help information,
Type: n to add a new partition.
Type: P and select add primary partition.
Type: L and select the primary Partition Number as 1. In this way, the primary partition created is sdb1.

Then, fdisk will let you select the start value and end value of the partition and press Enter.
Finally, type w to save all and exit to complete the partition of the new hard disk.

3. format the disk.
Enter mkfs-T ext3/dev/sdb1 on the terminal
Format/dev/sdb1 in ext3 format

4. Mount the partition:
Manual mounting:
Enter mkdir/data on the terminal to create a mount point for the new hard disk.
Type Mount/dev/sdb1/data on the terminal and mount the new partition to the/data/directory.
Modify the/etc/fstab file and add the following lines:
/Dev/sdb1/Data ext3 defaults 0 1
