Increase disk space of a new AlgoSec VM

The following topic explains how to increase the disk space of a newly deployed AlgoSec VM (running CentOS 7) by extending your out-of-the-box VM hard disk.

The AlgoSec OVF comes with 241 GB in the data partition. After you deploy it on a VMware environment, according to your sizing, you may need to increase the disk space of your newly deployed AlgoSec VM.

    sda should contain both sda1 and sda2.

Do the following:

  1. On the VM, click Actions and select Edit Settings.

  2. On the Virtual Hardware tab, change the disk size of the Hard Disk.

  3. Click OK.
