OCI Storage Environment
In the OCI environment, you can, for example,
- create a new storage volume (a block 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 Oracle Cloud documentation.
Creating a New Volume
| Step | Details |
|---|---|
| Open the Block Storage configuration from the Core Infrastructure menu section. |
This will open the block volume list. |
| Click on Create Block Volume to create a new virtual disk. |
This will open the block volume creation screen. |
| Enter the details of the new volume. | Add at least
Adapt the other settings as required. When done, click on Create Block Volume.
If you chose to view the volume details after the volume has been created, the detail screen will be displayed. |
Return to the instance list to attach the new volume to your instance.
Attaching an Existing Volume to an Instance
After returning to the instance list (via Compute > Instances), select your instance to display the instance details. Then perform the following steps to attach the block volume to your instance:
| Step | Details |
|---|---|
| Select Attached Block Volumes from the Resources section on the left. |
In the example above, no volumes have been attached so far. Click on Attach Block Volume to select the volume that is to be attached. |
| Select the parameters for the volume and attach it to the instance. | Select which block volume to attach, the parameters for attaching the device (paravirtualized, read/write), the compartment, and the device path presented to the Charon-SSP host.
Once all parameters have been set, click on Attach. |
| Verify that the device has been attached. | The instance details list now shows the attached volume.

Detaching a Volume from an Instance
First, unmount the volume in the Charon host system (see Charon-SSP Manager section below).
Then detach the volume from your instance:
- Go to the Attached Block Volumes list in the instance details display.
- Click on the three dots next to the volume to be detached and select Detach.

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 > Oracle 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.
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.
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 > Oracle Cloud > Storage Manager.
- Select the volume.
- Click on the cogwheel symbol and select Unmount the Filesystem.
