The data disk

This article explains how to expand the capacity of SGBox’s data disk. Using LVM partitions you can add new disks and show them as a big single disc.
In order to extend disk

Requirements:

  • Sgbox must support LVM partitions: in the login screen there is an L next to the version number.
  • You have to add a new disk to the virtual machine.
  • SGBox must be updated to version 4.0.0.

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

Select Hard disk management

Re-enter cli user password.

In our case, we see that:

  • The hard disk sda: has a partition ( sda2 ) with the LVM configured (vg_sgbox-lv_sgbox)
  • New added disk appears with sdb and is not partitioned
