Volumes
Create, attach, detach, and clean up tenant block storage volumes.
Volumes provide persistent block storage for instances. Use them for data that should survive instance rebuilds or for workloads that need storage independent from the VM lifecycle.
💾 Volumes can outlive instances
Deleting a VM does not always delete attached or separately created volumes. Check storage after cleanup so unused volumes do not keep consuming quota.
Create
Choose a name, size, and volume type that fit the workload and quota.
Attach
Attach the block device, then format and mount it inside the guest OS.
Detach or delete
Stop writes, unmount inside the VM, detach, then delete only when data is no longer needed.
Terraform
Keep volumes and attachments in code when the stack should be repeatable.
Create a volume
- Open Volume or Storage, then Volumes.
- Choose Create Volume.
- Enter a name, size, and volume type if the project exposes volume types.
- Create the volume and wait for it to become available.
Volume capacity counts against project quota. Choose the smallest size that fits the workload and expand later if needed.
Attach a volume to an instance
- Open the volume actions menu.
- Choose Attach.
- Select the instance.
- Confirm the attachment.
- Inside the VM, format and mount the device if it is new.
Skyline attaches the block device to the VM. The guest operating system still controls partitioning, filesystems, mount points, and application data.
Detach or delete a volume
Before detaching, stop applications that write to the volume and unmount it inside the VM.
⚠️ Unmount before detach
Detaching a volume while the guest OS or application is still writing can corrupt data.
To delete a volume:
- Confirm it is detached.
- Confirm no snapshots or backups are still needed.
- Delete it from the volume list.
Deleting an instance does not always delete attached or separately created volumes. Check the volume list after instance cleanup so unused storage does not keep consuming quota.
Use volumes with Terraform
Terraform is a better fit when volumes, attachments, instances, and security groups should be created together. If Terraform manages a volume, inspect it in Skyline but make lasting changes in Terraform code.
