| To create a new virtual disk for an existing Linux virtual machine: | |
| Log in as root on your Linux virtual machine. | |
| Run this command and make note of the sdx entries | |
| ls /dev/sd* | |
| Log in to the vCenter Server using the vSphere Client. | |
| In the vSphere Client inventory, right-click the virtual machine and select Edit Settings. | |
| Click the Hardware tab and click Add. | |
| Select Hard Disk and click Next. | |
| Complete the wizard. | |
| Reboot the Linux virtual machine. | |
| Log in using the root credentials. | |
| Running the command ls /dev/sd* will now return a new entry. | |
| Create an ext3 file system on the new disk using the new sdx from step 10. | |
| mkfs -t ext3 /dev/sdx | |
| You may see an alert that you are performing this operation on an entire device, not a partition. That is correct, as you created a single virtual disk of the intended size. This is assuming you have specified the correct device. | |
| Caution: Ensure you have selected the right device, there is no undo. | |
| Run the fdisk command to verify the existence of the disk you created: | |
| fdisk -l | |
| Run this command to create a mount point for the new disk: | |
| mkdir / New_Directory_Name | |
| Run this command to display the current /etc/fstab: | |
| cat /etc/fstab | |
| Using a text editor, edit fstab and add this line to add the disk to /etc/fstab so that it is available across reboots: | |
| /dev/sdx /New_Directory_Name ext3 defaults 1 3 | |
| Note: Use a Linux text editor of your choice. | |
| Restart the Linux virtual machine and the new disk is now available. |
