How To Delete a Volume Stuck in "Reserved" State

Problem

Users may encounter situations where a block storage volume cannot be deleted because it is stuck in the reserved state.

This condition usually occurs when a volume operation (such as attach, detach, or delete) was initiated but did not complete successfully. As a result, the volume remains marked as reserved in the database even though it is not actively attached to any instance.

When a volume is in this state, attempts to delete it will fail until the state is manually reset.

Example output showing a volume stuck in reserved state:

The volume service list has multiple volumes in down state:

Example

$ openstack volume show <VOLUME_UUID>
+--------------------------------+-------------------------------+
| Field                          | Value                         |
+--------------------------------+-------------------------------+
| id                             | [VOLUME_UUID]                 |
| status                         | reserved                      |
| size                           | [VOLUME_SIZE]                 |
| attachments                    | []                            |
| multiattach                    | False                         |
| name                           | [VOLUME_NAME]                 |
| bootable                       | false                         |
| created_at                     | [CREATION_TIMESTAMP           |

Environment

• Private Cloud Director Virtualization - v2025.10 and Higher

• Self-Hosted Private Cloud Director Virtualization - v2025.10 and Higher

Procedure

These steps can only be run as admin. Source the RC file with the admin credentials.

$ source <RC_FILE>

1. Identify the Volume - Retrieve the volume UUID.

$ openstack volume list

1. Reset the Volume state to Available:

$ openstack volume set --state available <VOLUME_UUID>

1. Delete the Volume:

$ openstack volume delete <VOLUME_UUID>

Validation

Verify that the volume has been successfully deleted.

$ openstack volume show <VOLUME_UUID>

If the volume is deleted successfully, the command should return a message similar to:

No volume with a name or ID of <VOLUME_UUID> exists.
