How to Manage Attachments for Vultr File System Volume

Learn how to connect and manage Vultr File System volumes with your instances for shared storage access.

Attaching a Vultr File System volume to a Vultr Cloud Compute instance allows the instance to discover the serverless volume as a new storage device. You can then mount the Vultr File System volume to share files across different Vultr Cloud Compute instances. You can remove a Vultr File System volume from a Vultr Cloud Compute instance.

Follow this guide to manage attachments for Vultr File System volume using the Vultr Customer Portal or Terraform.

  • Terraform
  1. Open your existing Terraform configuration for the File System volume (and instances).
  2. Attach: set attached_instances on the vultr_vfs resource and apply.
    terraform
    resource "vultr_vfs" "file_system" {
    # ...existing fields (label, region, size_gb)
    attached_instances = [
        vultr_instance.app1.id,
        # vultr_instance.app2.id
    ]
}
  3. Detach: remove instance IDs from the list (or set it to an empty list), then apply.
    terraform
    resource "vultr_vfs" "file_system" {
    # ...existing fields (label, region, size_gb)
    attached_instances = []
}
  4. Ensure each instance has Memory Backing set to “Shared” (Settings > Change Memory Backing > Shared) before attaching.
