Storage

Create and manage block storage volumes for your instances.

Volumes provide persistent storage that remains available even if an instance is deleted.

With an agent (MCP)

Connect the redu MCP, then just ask your agent. It calls create_volume to provision the volume and list_volumes to find it. To attach a volume at launch, the agent includes it when it runs create_instance.

Create a 50 GB volume for me.

1. Create a volume

Go to:

Menu → Block Storage → Volumes

Then:

1. Click Create Volume
2. Enter a name (for example data-volume-01)
3. Set the size in GB
4. Optionally add a description
5. Submit the form

The size must be between 1 and 2048 GB. The creation form shows the storage price before credits when pricing is available.

Notes

• Choose a size that fits your needs
• Volumes can be detached and reused across instances
• Wait for status available before attaching a new volume

The volumes list shows:

2. Attach a volume

To attach a volume to an instance:

1. Open the volumes list and find an available volume
2. From Actions, select Attach to Instance
3. Choose a Virtual machine in the Attach Volume dialog
4. Click Attach Volume

The status changes while the operation runs. Do not try to mount the device until the list shows the target instance under Attached To.

After attaching, log in to the instance and mount the volume.

Example (Linux)

# Create filesystem (only once)
sudo mkfs.ext4 /dev/vdb
 
# Create mount point
sudo mkdir -p /mnt/data
 
# Mount volume
sudo mount /dev/vdb /mnt/data
 
# Optional: persist across reboots
sudo blkid /dev/vdb

3. Detach a volume

Before detaching, unmount the volume inside the instance to avoid data loss.

sudo umount /mnt/data

Then:

1. Open the volumes list
2. From Actions, select Detach Volume
3. Review the warning and click Detach Volume

Wait for the volume to return to available before attaching it elsewhere or deleting it.

4. Delete a volume

Only delete volumes you no longer need.

1. Ensure the volume is detached
2. From Actions, select Delete Volume
3. Confirm

Deletion is permanent.
