Public bug reported:

This bug was originally reported downstream [1][2], where a BFV server
create failed due to exceeding server group member quota and leaves the
volume in the "reserved" state, which prevents users from using the
volume or deleting the volume.

The workaround for this is to delete the volume attachment in Cinder,
which will return the volume to the "available" state. For example:

$ openstack --os-volume-api-version 3.27 --os-cloud devstack volume attachment list 
+--------------------------------------+--------------------------------------+--------------------------------------+----------+
| ID                                   | Volume ID                            | Server ID                            | Status   |
+--------------------------------------+--------------------------------------+--------------------------------------+----------+
| d4470d80-ec1d-480c-8c59-1b3ff2f3985f | a4ef4a82-6aad-4637-8759-e01bb706ef2f | c6e2f02e-a408-4a5f-a325-55481a7d5c61 | reserved |
+--------------------------------------+--------------------------------------+--------------------------------------+----------+

$ openstack --os-volume-api-version 3.27 --os-cloud devstack volume
attachment delete d4470d80-ec1d-480c-8c59-1b3ff2f3985f

After that the volume should be in 'available' state and able to be
deleted.


To fix the bug, we will need to have Nova delete the "reserved" volume attachment if quota is exceeded for server group members.
