# E2003 — Volume operation rejected (E\_VOLUME\_NOT\_FOUND\_FOR\_OWNER)

| Property | Value |
| - | - |
| **Code** | `2003` |
| **Slug** | `E2003` |
| **Category** | `storage` (Storage) |
| **CIP** | CIP-9 |

## What happened

Volume operation rejected (E\_VOLUME\_NOT\_FOUND\_FOR\_OWNER): \{detail}.

This is the receipt's `what` text, produced by the node's `ExecutionError::RasVolume`. Placeholders in braces are filled from the failing transaction.

## Why it happened

The node rejected the operation with `E2003` (category `storage`, Storage). The receipt's `why` field carries the specific cause and `context` carries structured details, such as the values that filled the placeholders above.

The normative rule is in CIP-9.

## How to fix

No volume with this name exists under the authenticated owner. Name lookups are owner-scoped: verify you are authenticated as the owner that created the volume.

## Receipt example

```json theme={null}
{
  "code": 2003,
  "slug": "E2003",
  "category": "storage",
  "what": "volume operation rejected (E_VOLUME_NOT_FOUND_FOR_OWNER): {detail}",
  "fix": "No volume with this name exists under the authenticated owner. Name lookups are owner-scoped: verify you are authenticated as the owner that created the volume.",
  "docs_url": "https://docs.cowboy.inc/errors/E2003"
