Use the Storage tool to expand the storage space for the Boot partition (Hard Disk 1) and the /vastorage (virtual appliance storage) partition (Hard Disk 2) that you created when you deployed the appliance. You can also expand the /varpartition if you created a separate disk for the log files.
To expand the size of an appliance disk partitions:
Log in to the Appliance Management Console as the vaadmin user.
Click Storage .
Use the tools provided by your virtualization platform vendor to expand the virtual disks that contain the partitions you are expanding.
In the virtual disks table, select the partitions to be expanded.
Click Expand partitions.
This action stops the appliance services, expands the selected partitions to the size of their respective disks, and restarts appliance services.
Restart the appliance so the operating system can detect the disks that have been expanded.
