2. To determine the size of the database, run this command on the vCenter Server Appliance and make a note of the size of /storage/db:
   
   df -h
    
3. Connect to the ESXi host were the vCenter Server Appliance is located with the vSphere Client.
4. In the Hosts and Clusters view, right-click the vCenter Server Appliance virtual machine and click Edit Settings.
5. Click Add.
6. Click Hard Disk, then click Next.
7. Select Create a new virtual disk then click Next.

6. Format the partition by running this command:
   
   mkfs -t ext3 -j /dev/drive_name
    
7. Create a temporary mount-point by running this command:
   
   mkdir /storage/tmp2
    
8. Mount the new VMDK by running this command:
   
   mount -t ext3 /dev/drive_name /storage/tmp2
   
   Note: The storage is mounted temporarily and does not persist after a reboot of the vCenter Server Appliance.
