Storage

Create and manage block storage volumes for your instances.

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

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

Notes

• Choose a size that fits your needs
• Volumes can be attached and reused across instances

2. Attach a volume

To attach a volume to an instance:

1. Open the volumes list
2. From Actions, select Attach to Instance
3. Choose the instance
4. Confirm

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. Confirm

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.
