IT Administrators deploying BDRShield Backup Server on VMware VM using the BDRShield VMware Virtual Appliance often start with a 1 or 2 TB volume for storage. As data grows, there might be a need to expand the disk to accommodate more backup data.

Follow these steps to increase the storage space of an existing storage volume:

1. Stop Services:

1. Login to the BDRShield machine.
2. Stop BDRShield, MySQL, and Mongo services using the following commands:
   

     /etc/init.d/mysql stop

     /etc/init.d/mongo stop

     /etc/init.d/vembubdr stop

2. Power Off VM:

Power off the BDRShield Backup Server VM from the VMware vSphere Client.

3. Edit VM Settings:

1. Right-click the VM and select "Edit Settings."
2. Choose the exact hard disk and increase the provisioned storage size according to your requirements. 

 Note: VMware vSphere allows users to Hot-Add storage size up to 2 TB without powering off the VM.

1. Save the configuration and power on the VM.
   

4. Terminal Commands:

1. Login to the VM and open the terminal.
2. Switch to sudo user and run the following command to check if the increased storage size updated properly:
   

       cat /proc/partitions

1. Then run the below command to resize the existing storage volume. Until you run this command, the increased storage will not be allocated to the mount point.
   

       resize2fs /dev/sdb

                  For Example: `resize2fs /dev/sdb`

1. This process may take time based on the used data.
   

5. Verification

Verify the changes by checking the disk space using the "df" command:

  df -a

6. Start Services:

Start Vembu BDR, MySQL, and Mongo services using the following commands:

     /etc/init.d/mysql start

     /etc/init.d/mongo start

     /etc/init.d/vembubdr start

7. Check User Interface:

Login and check the Vembu BDR backup server user interface to ensure proper functionality.
