Extend the entire disk size

This article explains how to expand the capacity of SGBox’s disk. With version 5 is possible extend the full disk, not only the data partition. In order to extend the disk:


  • SGBox version 5 is required.
  • You need to extend SGBox disk from your hypervisor.
  • ⚠️ It may be necessary to reboot the machine after expansion on the hypervisor

Connect in ssh (using for example Putty program) to SGBox specifying the user cli.
If you haven’t changed them through the wizard, the default credentials are:

user: cli
pass: CL1changePW
