We do not support resizing partitions on active installations. You can create a backup of your current installation and restore it to a new installation of the same version of Genian NAC.
You can see instructions on how to obtain and restore a backup image here.
To add the backup image to your newly installed system, login to the CLI on the Policy Server:
Enter the command 'enable' and authenticate to enter the privileged mode.
To retrieve this file to another machine, you must enter the shell mode using the command '@shell' from the privileged mode. This command will not be visible on screen.
Use the command 'scp [user]@[IP]:[source path] /disk/data/DBBACKUP' to retrieve the backup file from the machine it was downloaded to. This machine must support ssh access. For example:
'scp email@example.com:/home/scott/ALDER-88909-20200902-150143.tar.gz /disk/data/DBBACKUP'
Enter command 'exit', and then reauthenticate to the CLI, re-enter the 'enable' command, and reauthenticate again.
Use the command 'do restore [backup name without file extension]' to initiate the restore process, and follow the onscreen prompts.
For example: 'do restore ALDER-88909-20200902-150143'
