Public bug reported:
What happens:
I have two regions and one availability zone (AZ) for my Essex cluster.
When creating a volume I accidentally used the region name instead of
the AZ name. This resulted in a volume being stuck in the "creating"
state which I cannot delete.
What I expect:
I expect two things:
1. The volume creation should fail (it currently does)
2. The volume to go into an "error" state (it does not currently do this)
Reasoning:
Having the volume go into an error state informs the user that there was
a problem and does not leave them wondering if they should wait longer
in case the command hasn't completed.
Steps to reproduce:
1. user@laptop:~$ euca-create-volume -s 2 # command requires a zone
These required options are missing: zone
2. user@laptop:~$ euca-create-volume -s 2 -z lcy-2 # accidentally pass a
non-existant zone name
VOLUME vol-00000001 2 lcy-2 creating
2012-06-21T13:50:10.074Z
3. user@laptop:~$ euca-describe-volumes vol-00000001
VOLUME vol-00000001 2 lcy-2 creating
2012-06-21T13:50:10.000Z
4. The nova-scheduler log file shows the following.

2. user@laptop:~$ euca-create-volume -s 2 -z nova # create the volume passing
in the correct AZ name

2012-06-21T14:02:07.000Z
Note the two volumes that have failed and will not complete and the
correctly created volume.
Ideally, I would like the API server to reject the command and return an
informative error message to the user before attempting to create the
volume.
