Title:
Error message is too generic when boot with volume creation fails with
exceeded quota
Status in OpenStack Compute (nova):
Fix Released
Bug description:
The message is "InvalidBDM: Block Device Mapping is Invalid."
Exceeding quota is a problem that should be solved by the user, not a
cloud admin. So the message should be one telling the user that the
error was caused by quota.
Example:
A user has 2 GB of volume quota.
ubuntu@dev-1:~/devstack$ cinder quota-usage b926f718a7d345cb9f57b4e4dc98f674
+-----------------------+--------+----------+-------+
| Type | In_use | Reserved | Limit |
+-----------------------+--------+----------+-------+
| backup_gigabytes | 0 | 0 | 1000 |
| backups | 0 | 0 | 10 |
| gigabytes | 0 | 0 | 2 |
| gigabytes_lvmdriver-1 | 0 | 0 | 2 |
| per_volume_gigabytes | 0 | 0 | -1 |
| snapshots | 0 | 0 | 10 |
| snapshots_lvmdriver-1 | 0 | 0 | -1 |
| volumes | 0 | 0 | 10 |
| volumes_lvmdriver-1 | 0 | 0 | -1 |
+-----------------------+--------+----------+-------+
Then, create an instance with 3 GB volume creation
ubuntu@dev-1:~/devstack$ nova boot --flavor m1.tiny --block-device
source=image,id=535ec234-5522-4cdc-598-4050a62d5135,dest=volume,size=3,bootindex=0

Fails with a message "Failure prepping block device". It is difficult
to know the quota is a cause of the error by seeing the message.
