===== How To Expand The Hard Drive Of A Virtual Appliance =====


**DESCRIPTION:**

This article will explain how to expand the logical volume size of a Virtual appliance to grow beyond the 250 GB and 950 GB OVA templates provided on MySonicWall.com. This process does not overwrite the pre-existing data, it will add on more space to the pre-existing Hard Drive.

***This process should not be used to expand the volume of Flow Server agents, or GMS 9.0 deployments installed with Flow Based reporting.**

***This process should not be used on GMS versions 8.1 or older.  Please upgrade to minimum GMS version 8.2 prior to performing these steps.**

===ADD A NEW VIRTUAL HARD DRIVE===

  1. Turn off the Virtual Appliance
  2. Log into the VMware Web Client or vSphere Client
  3. Select Edit Settings for the Virtual Appliance
  4. Click the Add button, and select the Hard Disk as the device type then select Next

===EXPAND THE VIRTUAL HARD DRIVE===

  1. Contact Technical Support to get the Root SSH password Best method is to open a Web ticket requesting Root SSH with this KB ID in the Title
  2. Check that the disk has been partition by running (should be listed as /dev/sdb1): **fdisk -l**

  3. First unmount the new device with the command: **umount /dev/sdb1**
  4. Create a Physical Volume (PV) with the following command: **pvcreate /dev/sdb1**
  5. Extend the Volume Group (VG) size to use the new PV with the following command: **vgextend datavg /dev/sdb1**
  6. Extend the Logical Volume (LV) size to use all of the VG free space with the following command: **lvm lvextend -l +100%FREE /dev/datavg/datalv**
  7. Resize the entire file system with the following command: **resize2fs -p /dev/mapper/datavg-datalv**  
(This command can take a little bit depending on the amount of space being added)
