To add additional disk storage to your Charon-SSP GCP instance (for example, for storing virtual disk containers), perform the steps described below.

GCP Storage Environment
In the GCP environment, you can, for example,
- create a new storage volume,
- attach an existing storage volume to your instance,
- detach a storage volume from your instance.
These steps are shown below.
For more details, please refer to the AWS documentation.
Creating a New Volume

Attaching an Existing Volume to an Instance
Once a volume has been created, you can attach it to your instance.

Detaching a Volume from an Instance
If the volume is the root device of the instance, you must stop the instance before detaching the volume.
If the volume is not the root device of the instance, unmount the volume in the Charon host system before detaching it (see Charon-SSP Manager section below).
Then detach the volume from your instance:

Storage Manager of the Charon-SSP Manager
Mounting a Newly Attached Volume
After the volume has been attached to the instance, it must be included in the Charon-SSP host system configuration. This is achieved via the Charon-SSP Manager.
- Open the Charon-SSP Manager on your local system and connect to your Charon cloud instance.
- Select Tools > Google Cloud > Storage Manager.
- In the Storage Manager window, perform the following steps:
- Select the new device.
- Click on the cog-wheel symbol.
- Only if required, select Format Volume to create a filesystem on the new device.
Please note: This will delete all data on the volume. - Click on the cog-wheel symbol and select Mount the Filesystem.
This will mount the new volume under /charon/storage/media/<UUID>/. The following image shows a sample:
Once the filesystem has been mounted, the space is available to the Charon-SSP host system. After the first mount via the Storage Manager, the filesystem will be automatically mounted after a restart of the Charon host instance.
Unmounting a Volume
To unmount a volume before perform the following steps:
- Stop all Charon instances that might use the volume that is about to be unmounted.
- In Charon Manager go to Tools > Google Cloud > Storage Manager.
- Select the volume.
- Click on the cogwheel symbol and select Unmount the Filesystem.
