Depending on your environment you may need to enlarge the virtual disk on which GreenLight stores its data on.
Please note that all virtual disks have to be located on the same physical storage. 
Please also note that extending disk space ALWAYS means that you have to add a new additional disk on virtual hardware level. I. e. extending disk space never means enlarging existing disks

In order to enlarge the partition in the GreenLight Appliance, perform the following steps:

1. The easiest way to enlarge a partition in GreenLight is to use the installed partition manager manager GParted. Please launch it using the Applications menu (you can also start GParted from the Terminal with "sudo gparted"):

6. From the Createas drop down menu, select PrimaryPartition and chose lvm2pv as File system (if needed, a Label can be defined):
   
   
   
7. Save your changes by clicking the the apply button - also on the popup message
   
   
   
8. Start the the LogicalVolumesManager from  from the Applications menu
